产品型号: 61-6998-71
产品品牌: SIGMAKOKI CO., LTD.
功能
- A dichroic filter that reflects or absorbs infrared and ultraviolet rays and transmits only visible light.
- It is used to extract only visible light from the blackbody radiation of tungsten halogen lamps and high-temperature furnaces.
- This device has excellent weather resistance and can be used in high temperature and high humidity environments.
- * If the incident angle is tilted to 15 degrees or more, the wavelength characteristics of reflectivity and transmittance will change, and the characteristics as specified will not be obtained.
- * There is no anti-reflection coat on the back.
- * This can cause ghosting due to reflections on the back and front surfaces.
