The New Standard in High-Performance Night Vision Optics
Developed in-house by our dedicated R&D team, the IP40 Lens Assembly represents a significant leap forward in PVS-14 compatible optics. Engineered specifically for the tactical end-user, this system prioritizes a build that is exceptionally rugged yet remarkably lightweight — solving the critical challenge of neck and head fatigue during long-duration missions.
Optical Quality on Par with the Industry Benchmark — At a Fraction of the Cost
The IP40 shares the same fundamental optical foundation as the widely respected Carson (Noctis Technologies) mil-spec lens assembly: precision optical glass elements and fully multi-coated (FMC) surfaces on every lens. Where the IP40 goes further is in its advanced aspherical optical design, which actively corrects edge distortion that standard spherical lens systems — including traditional mil-spec designs — cannot eliminate.
Our proprietary FMC broadband coatings, applied to every glass surface, deliver maximum light transmittance and high contrast in low-light conditions, ensuring that every lumen your image intensifier produces reaches your eye.
Significantly Lighter. Meaningfully Better for the Operator.
Weight is a mission-critical factor. Here is how the IP40 compares directly to the Carson mil-spec lens assembly:
| Â | IP40 (INFREDAR) | Carson Mil-Spec |
|---|---|---|
| Objective Assembly Weight | ≤42g | 53.3g |
| Eyepiece Assembly Weight | ≤60g | 73.6g |
| Combined Weight | ≤102g | 126.9g |
| Weight Saving | ~20% lighter | Baseline |
| Housing Material | PEEK polymer | Aluminum alloy |
| Lens Material | Optical glass | Optical glass |
| Lens Coating | Full Multi-coated (all surfaces) | Multi-coated (all surfaces) |
| Exit Pupil Diameter (Eyepiece) | ≥14mm (on axis) | ≥14mm (on axis) |
| Eye Relief (Eyepiece) | 29mm | 25mm |
| Field of View | ≥40° | 40° |
| Immersion Rating | 20m / 2 hours | 20m / 2 hours |
The IP40’s PEEK housing achieves this weight reduction without compromising structural integrity. PEEK is a high-performance engineering polymer used in aerospace and medical-grade applications, offering comparable strength to aluminum at significantly lower weight.
Why the IP40 Makes Sense
The Carson mil-spec lens assembly has long been considered the gold standard of PVS-14 optics — and rightfully so. The IP40 was designed with that benchmark in mind: matching Carson’s optical glass construction, full-surface multi-coating standard, equivalent exit pupil diameter (≥14mm on axis), and the same 40° field of view operators depend on.
Where the IP40 delivers a clear and measurable advantage:
1. Lighter on Every Mission The IP40’s combined assembly weighs ≤102g, approximately 20% lighter than the Carson mil-spec set at 126.9g. Over extended head-mounted operations, this reduction in load directly translates to less neck fatigue and sustained operator effectiveness.
2. Superior Eye Relief With an eye relief of 29mm, the IP40 exceeds the Carson mil-spec standard of 25mm. This added distance provides greater comfort and flexibility for operators wearing eyewear or using the device in dynamic conditions.
3. Better Edge-to-Edge Clarity The IP40’s aspherical optical elements actively correct the edge distortion inherent in standard spherical lens designs, including traditional mil-spec configurations. The result is a sharper, more consistent image from center to periphery.
4. Purpose-Built for Modern Procurement The IP40’s significantly lower acquisition cost makes high-performance optics accessible for larger procurement volumes, fleet replacements, and OEM integration — without compromising on optical quality or durability.
For professional buyers, government agencies, and system integrators who require mil-spec-level optical performance at a realistic price point, the IP40 is a compelling, field-proven alternative.
