Produces invisible infrared illumination in the 850nM range which requires the use of night vision devices to be seen.\r\u003cbr\u003e850 nm cut off infrared lens blocks the projection of all visible light. The borosilicate substrate (commonly known as Pyrex) has the durability of tempered glass and is coated on both sides. The lens is sealed into the machined aluminum housing. The housing is attached via bracket and thumb nuts. The lens and lens holder are insulated\/sealed with high temperature silicone and high temperature silicone gaskets to prevent light leakage.\r\u003cbr\u003eThe lens holder assembly can be attached and removed quickly. Once secured, the unit can subjected to excessive vibration without risk of the lens exposing the visible light. This milspec unit enables 93% of light energy to pass through the filter. Plastic infrared filter lenses usually allow only 20% of the light energy to pass. This means that the RL-11 HID light will only lose 7% of its 3000 foot beam due to the lens. Other lights using the plastic lens will lose up to 80% of the transmission length.\r\u003cbr\u003eThe light output produced with the use of this lens is invisible to the naked eye. Night vision cameras, goggles and similar devices are needed to view the output from this lens.\r\u003cbr\u003eTHIS INFRARED LENS COVER ASSEMBLY IS MADE IN THE USA\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003eUse With: \u003cbr\u003eWavelength:   850nM \u003cbr\u003eMaterials:  Machined Aluminum - Pyrex™ Lens \u003cbr\u003eEfficiency 93% Light Energy Passage\u003cbr\u003eHardware:  Steel Bracket - Thumb Nuts\u003cbr\u003eSpecs:  Milspec\u003cbr\u003e","brand":"Larson Electronics","offers":[{"title":"Default Title","offer_id":38342920110261,"sku":"PL3-RL-11-IRF","price":1838.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/PL3-RL-11-IRF-1.jpg?v=1611583606","url":"https:\/\/getcahits.com\/fr\/products\/pl3-rl-11-irf","provider":"PuriLite","version":"1.0","type":"link"}
