The 87-050 is a Dichroic Longpass Filter, measuring 25.2 x 35.6 mm with a thickness of 1.05mm, sourced from the renowned optical vendor, Edmund Optics. This filter is designed to transmit light at wavelengths above 1200nm, making it ideal for applications that require the separation of infrared light.
The filter is constructed from UVFS Mal-1965, a material specifically chosen for its optical properties. It boasts a cut-on wavelength of 1200nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths below this point.
The 87-050 features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This makes it suitable for use in high-precision optical systems. The filter is coated on both the front and back with EDM 87-032, a coating that enhances its performance and durability.
