The 49-093 is a 25 mm diameter Heat Absorbing Glass IR Cut-Off Filter, designed for applications within the 300-2700nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is identified by the catalog number 49-093.
The filter is made of SCHOTT KG5, a high-quality glass material known for its excellent optical properties. It is designed in a circular shape, with a diameter of 25 mm and a thickness of 3 mm, providing a robust and compact solution for various optical setups.
The 49-093 features a unique coating on both the front and back surfaces, identified as EDM 49-092. This coating enhances the filter's performance, particularly in terms of its cut-on and cut-off wavelengths. The cut-on wavelength is 300nm, while the cut-off wavelength is 2700nm, making this filter ideal for applications that require precise infrared (IR) cut-off capabilities.
The filter's geometry is shaped as a thin lens, which is beneficial for applications that require minimal optical path length distortion. This feature, combined with its wide wavelength range and precise cut-off characteristics, makes the 49-093 a versatile and reliable choice for various optical systems.
