Deskripsi Produk

Product Description

 Round Diameter 26.5mm And 1.5mm Thick Cyan Glass Visible Pass IR Cut Filter For Camera  

 

Infrared (IR) cut-off filters are used with color CCD or CMOS imagers to produce accurate color images.  An IR cut-off filter blocks the transmission of the infrared while passing the visible.This can be done with two optical techniques: absorption or reflection.  Absorptive filters are made with special optical glass that absorbs near infrared radiation.  Reflection type filters are short-pass interference filters that reflect infrared light with high efficiency.
We offer both types of absorptive filters and reflective IR filters, which is a new type of reflective filter suitable for day/night security cameras.  It allows both visible and infrared LED light to pass through.  The absorptive filters are recommended for CCD imagers while the reflective CMOS imagers.

Technical Information

What is infrared?
Infrared (IR) is invisible radiant energy, electromagnetic radiation with longer wavelengths than those of visible light. Human eyes only can see light with a wavelength between 320nm-760nm. Infrared, which spans 700nm to 1000nm on the EM spectrum, is beyond what the human eye can see, but the IP camera sensor can detect it and make use of it.

 

What does IR-cut do?
IR-cut (Infrared cut-off filter) is a mechanical shutter design. It is placed between the lens and the image sensor, and is controlled by a motor or an electromagnet.
It is designed to block or deliver the infrared in order to provide a true color reproduction high-quality image at day and night.

Processing

Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.

 

Testing

Oplens equipped Zygos which work by producing a beam of laser light and transmitting it to the optic under test by way of a very, very accurate lens fitted to the Zygo. This is the key to the instrument's accuracy. As the light passes through this lens, which is not coated, it enables 4% of the light to be reflected back into the Zygo.

 

Company Profile

 

Sichuan JUKA Optical Technology Co., Ltd. is a professional company specializing in high-precision optical lens, prisms, and window,etc. Company is located in Chengdu of China, which enjoys the fame of world-wide optical processing center. JUKA's predecessor was the Optical Processing Department of the Institute of Optoelectronic Technology, Chinese Academy of Sciences,which was established in 1988. And company switched successfully to be a private enterprise from a state-owned enterprise in 2005.

JUKA Optics has first-class processing and detection equipments, which include more than 100 sets of processing equipments, 2 sets of Zygo interferometers and 1 set of Veeco interfermeter. Chengdu Juka also has a large number of excellent engineers for optics, machnism,electricity and operation.
