The Marshall V-140-1.0 is built for professionals who demand extraordinary low-light imaging and long-range precision in a compact CS-mount package. Featuring a telephoto 140 mm focal length and an ultra-fast f/1.0 aperture, this lens delivers remarkable light-gathering capability, enabling sharp, high-contrast imagery in near-dark environments. Its transmittance spans Near UV, Visible, and Near IR up to 1,000 nm, providing versatile spectral access that supports a wide range of imaging applications—from standard daylight surveillance to covert infrared observation. Engineered with a focus on optical fidelity, mechanical reliability, and rugged field performance, the V-140-1.0 is suited for law enforcement, security, military, and critical infrastructure monitoring where every frame counts. Whether deployed on stationary platforms, mobile systems, or integrated into covert or remote setups, this lens is designed to maximize detection range, detail resolution, and target isolation without compromising image quality.

  • The combination of a fast f/1.0 aperture and a 140 mm focal length delivers exceptional light gathering and subject isolation, making it possible to capture clear, detailed images even when illumination is scarce. This enables operators to identify fine features, read subtle textures, and discern distant subjects with confidence in challenging environments while maintaining short shutter speeds and reduced motion blur.
  • Near UV, Visible, Near IR 1,000 nm transmittance provides flexible spectral imaging capabilities. By spanning these wavelengths, the V-140-1.0 supports applications such as enhanced contrast in shadowed scenes, material discrimination, and covert observation using infrared illumination without visible-light disclosure. The lens is optimized to preserve color fidelity and edge definition across the spectral range, giving operators diagnostic-quality imagery across diverse lighting conditions.
  • Telephoto reach with precise optical performance allows operators to monitor distant scenes, depict fine details on targets of interest, and maintain a safe operational distance. The 140 mm focal length reduces perspective distortion typical of wide-angle lenses while maintaining strong subject separation from backgrounds, which is essential for security surveillance, reconnaissance, and evidence capture in sensitive environments.
  • CS Mount compatibility ensures easy integration with a wide array of cameras and sensor formats commonly used in security and surveillance systems. This fixed lens is designed to mount securely to CS-mount housings, enabling quick swaps, straightforward maintenance, and compatibility with existing field deployments without requiring extensive adapter solutions or specialized housings.
  • Reliability and optical durability are central to the V-140-1.0’s design. Precision-crafted optics, robust mounting interfaces, and quality coatings contribute to consistent performance in a variety of conditions. Whether exposed to temperature fluctuations, dust, or vibrations, the lens aims to preserve image integrity and operating stability, making it a dependable option for mission-critical surveillance and covert operations.

how to install Marshall V-140-1.0

  • Before installation, verify that your camera system uses a CS-mount interface and that the lens thread pitch and diameter are compatible with the mounting hardware supplied by your enclosure or camera body.
  • Power down the camera and any connected equipment before attaching the lens to avoid electrical or mechanical damage during mounting.
  • Align the lens with the camera’s CS-mount interface, ensuring a snug, straight connection without cross-threading or excessive torque on the mount.
  • Securely tighten the lens to the camera using the appropriate locking mechanism or screws provided with the CS-mount kit, taking care not to overtighten to prevent damage to the lens housing or sensor assembly.
  • Once mounted, perform a basic optical check by powering on the system, focusing at infinity, and verifying that the image is sharp across the frame. Use manual focus to fine-tune for your target distance and scene, then lock the focus if the system includes a locking feature.
  • Calibrate exposure and white balance according to the lighting conditions and IR illumination used in your setup. For covert or IR-focused work, test under your specific illumination scenario to ensure target visibility and image clarity meet operational requirements.
  • Regularly inspect the mount for dust, debris, or signs of wear, and apply appropriate maintenance to preserve optical alignment and registration over time.

Frequently asked questions

  • Q: What applications is the Marshall V-140-1.0 best suited for? A: It is ideal for law enforcement, military, security, covert surveillance, and any field requiring extreme low-light imaging with long-range subject isolation, thanks to its 140 mm focal length and f/1.0 aperture combined with wide spectral transmission up to 1,000 nm.
  • Q: What does the spectral range include? A: The lens provides transmittance across Near UV, Visible, and Near IR wavelengths up to 1,000 nm, enabling versatile imaging options across lighting conditions and illumination sources.
  • Q: Is this lens compatible with standard CS-mount cameras? A: Yes. The V-140-1.0 is designed for CS-mount systems, allowing straightforward integration with many surveillance cameras and imaging platforms that support CS-mount interfaces.
  • Q: Can I use this lens for color as well as infrared imaging? A: The spectral capabilities support both visible and Near IR imaging, so you can capture color in daylight and switch to infrared-enhanced views when appropriate, depending on your illumination setup and sensor capabilities.
  • Q: How should I maintain the lens in field conditions? A: Keep the lens clean using appropriate optical cleaning methods, protect the housing from dust and moisture, verify mount integrity after transport, and periodically check focus calibration and locking mechanisms to ensure consistent performance.

Nice shirt!
Size: XX-Large, Color: Wine Red
We're pretty impressed with this shirt. It fits well and looks flattering. The design is simple and it seems to be appropriate for a wide variety of casual events. Most importantly, it is comfortable to wear. The material is soft and not too heavy, making it suitable for cooler days. It has a moderate amount of stretch and is of decent quality. I wouldn't mind owning more of these shirts in different colors, and the pricing is reasonable.

Looks & Feels Good!
Size: X-Large, Color: Wine Red
I got this shirt for my husband in wine red and he likes it a lot! He can be very picky, but he hasn't had any complaints about this shirt. The wine red color looks just like it does in the picture and it fits true to size. It can be worn on its own or layered under a shirt or sweater when the weather gets cold. Hubby has machined washed and tumble dried this shirt multiple times and it still looks and feels great!

Long sleeve tee
Size: XX-Large, Color: Wine Red, Size: XX-Large, Color: Wine Red
Ordered this one size up simply due to preference. It runs true to size otherwise. The material is stretchy and the color was accurate. The ribbing sets this apart from other plain long sleeve tees. The only thing I don’t like is the curved hem. Makes it look very girly.

Excellent fit and a good look
Size: Small, Color: Grey, Size: Small, Color: Grey
I'm very pleased with the way this shirt looks on me. Despite being a "squeeze" material, it's quite comfortable to wear. The fit, at least for me, is spot-on. Design-wise, I found that the lines on the front of the shoulders look a little odd, almost like they're supposed to the shoulder seams. But overall, I really like this shirt, and $20 for a shirt that fits this well is a steal.

Bizarre bottom hem shape
Size: Medium, Color: Wine Red, Size: Medium, Color: Wine Red
First, my stats: I’m 6 foot 1, 185 pounds. I ordered a medium size. At first glance, I liked this shirt, but after observing what the bottom looks like, I’m not even sure I want to keep this. A picture is worth many words, so take a look at the ones I included in this review. The bottom hem in the front curves down in a strange sort of “tunic” style. This renders the garment completely unwearable in my opinion, as this is not a shirt that I think would look good tucked into pants. If the bottom of the shirt was flat/straight, it would be four or five stars. As such, I’m rating this three stars because the only thing wrong with this shirt is the bottom, and this might not bother everyone else.
