87-044 25 mm Dia. Dichroic Longpass Filter; t=1.05mm 1200nm
The 87-044 is a Dichroic Longpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter, with a 25 mm diameter, is designed to transmit light with wavelengths above 1200nm, while effectively blocking wavelengths below this cut-on value.
The filter is constructed with a base shape of a Circular Thin Lens, ensuring efficient light transmission and minimal distortion. It has a thickness of 1.05mm, providing sufficient structural integrity for most applications. The material used in this filter is UVFS Mal- 1965, a common choice for optical filters due to its excellent optical properties.
The 87-044 filter is coated with EDM 87-032 on both the front and back surfaces, enhancing its performance and durability. This coating ensures consistent transmission and blocking characteristics, making it suitable for a wide range of applications.
