HPD645 25.5 x 36 mm Fluorescence Longpass Dichroic Filter 620-720nm

The HPD645 is a 25.5 x 36 mm Fluorescence Longpass Dichroic Filter, specifically designed for use in the 620-720nm wavelength range. This filter is sourced from the reputable vendor, MKS/Newport, and is available for purchase directly from their website.

The filter is a Longpass type, which means it allows transmission of longer wavelengths while blocking shorter ones. This is particularly useful in applications where specific wavelength selection is required. The HPD645 has a base shape of a Rectangle, making it suitable for various optical setups.

The filter is made from UVFS material, identified by the Mal-1965 Material ID. This material is known for its optical properties, making it an ideal choice for this type of filter. The filter has a thickness of 1mm, providing sufficient durability while maintaining minimal impact on the optical path.

The coating on both the front and back surfaces of the filter is 'new hpd645'. This coating is designed to enhance the filter's performance in its specified wavelength range. The filter's shape is Thin Lens, which suggests it may have some light focusing properties, although this is not its primary function.
