InfiRay CL42 Thermal Imaging

• Front-Mounted Thermal Design: The InfiRay CL42 Thermal Imaging clips in front of a day scope, so it adds thermal detection without changing the familiar handling of a conventional optic.
• No Re-Zeroing Concept: As part of the InfiRay Clip C family, it is built for use ahead of a day scope without re-zeroing, which saves time when moving between daylight and thermal setups.
• 384x288 Thermal Sensor: The microbolometer sensor with 17.00 μm pixel pitch and 50.00 Hz refresh rate gives a stable thermal image that is easier to track on moving animals and scan across mixed terrain.
• 42 mm Objective and 1500.00 m Detection Range: This combination gives the CL42 enough reach for field use where early heat-source detection matters more than fine visual detail.
• Compact, Weather-Resistant Housing: With a 154.00 mm length, 420.00 g weight and IPX-6 waterproofing, the unit adds thermal capability while remaining manageable on a hunting rifle in poor weather.

About the InfiRay Clip C Series

InfiRay Clip C is a thermal imaging attachment series built for shooters who want to keep using a conventional day scope while adding thermal capability for low-light and no-light work. The series is designed to mount in front of a standard day optic, which makes it especially relevant for hunters and field users who prefer the familiar eye relief, reticle and shooting position of their daytime setup. A key idea behind the Clip C line is no re-zeroing, so the attachment can be fitted quickly without turning the rifle into a dedicated thermal-only platform.

The series also stands out for its dual-use concept. With the appropriate optical monocular accessory, a Clip C unit can also serve as a handheld thermal monocular for scanning before the shot, reducing the need to carry separate thermal devices. InfiRay positions the range as a practical bridge between traditional optics and thermal imaging, with models such as the CL42, CH50, CH50 V2 and CH50W. Across the series, the emphasis is on compact front attachments, straightforward field handling and thermal observation for hunting and general outdoor use.

About the InfiRay CL42 Thermal Imaging

The InfiRay CL42 Thermal Imaging is a thermal clip-on intended for users who want thermal detection while keeping the shooting characteristics of a day riflescope. Its 3.00 x optical setup and 42.00 mm objective are aimed at practical field observation and target detection, while the front-attachment format lets the rifle remain configured around a familiar daytime optic. That matters in real use because the shooter keeps the same cheek weld, reticle picture and general rifle balance instead of adapting to a completely different sighting system.

At the core of the CL42 is a 384x288 microbolometer with 17.00 μm pixel pitch, 60.00 mK NETD and a 50.00 Hz refresh rate. In practice, this gives a smooth thermal image for scanning hedgerows, woodland edges and open ground, while the detection range of 1500.00 m helps pick up heat sources well before they are close enough for positive engagement. The 1024×768 Micro-HD display provides a clear viewing surface inside a compact housing, and the automatic or manual calibration modes let the user balance convenience with image consistency in changing conditions.

The CL42 is also built around portability. At 420.00 g and 154.00 mm long, it is compact enough to avoid making a rifle excessively front-heavy. Power comes from CR123 batteries with a stated 4.00 h battery life, which suits shorter outings or staged use from a pack. With IPX-6 waterproofing and fogproof construction, it is configured for wet, cold and changeable field conditions where thermal devices are often used most.

About IRay

IRay develops and manufactures infrared detectors, thermal camera cores and modules, and complete thermal imaging cameras. Within its outdoor segment, InfiRay Outdoor focuses on optoelectronic products for hunting and observation, including thermal and digital riflescopes, thermal and night-vision monoculars and binoculars, and thermal attachments. Its product families include handheld lines such as Eye II, Eye III, AFFO, Finder and Gemini, as well as riflescope and attachment series such as Holo, Rico, Tube, Mate and Clip C.

The company places strong emphasis on in-house thermal technology, identifying IC design, MEMS sensors and Matrix III image algorithms among its core technologies. That background is directly relevant to products like the CL42, where detector performance, image processing and compact system integration matter more than cosmetic features. In practical terms, IRay is known for building thermal devices that cover both dedicated sighting systems and add-on solutions for users who want to integrate thermal imaging into existing optics setups.
