Schneider Optics : LP 820 HT

Schneider-Kreuznach magnetron sputtered industrial longpass filters impress with steep slopes and high transmission at stable cut-on wavelengths. The very flat surface makes them ideal for high end machine vision systems in factory automation. All longpass filters come with superior antireflection coating. Schneider-Kreuznach longpass filters are RoHS conform. Custom sizes are available on request. What is the function of a longpass filter? A longpass filter selectively transmits light with longer wavelengths while blocking light with shorter wavelengths. The filter is designed to transmit light that is above a specific wavelength cuton, known as the filter's "cuton wavelength," and to reflect or absorb light that is below this wavelength. Where is a longpass filter used? In industrial applications, longpass filters are used to remove unwanted shorter wavelength light from a light source or to separate different wavelengths of light. For example, in fluorescence microscopy, a longpass filter can be used to block the excitation light and allow only the longer wavelength fluorescence emission light to be imaged.      

-> Average Transmission 95 %: Achieve an impressive average transmission rate of 95 % for optimal light throughput.
-> Steep slopes: Take advantage of steep slopes that allow efficient isolation of specific wavelengths.
-> Wavelength Tolerance +/- 1 %: Experience exceptional accuracy with a wavelength tolerance of +/- 1 %, ensuring precise results.
-> Ultra Low Reflection: They minimize reflections, resulting in better performance of optical systems.
-> Deep Blocking / High Optical Density: Interfering wavelengths are blocked and unwanted stray light is minimized.
