628-40 EX 25 mm Dia. Mounted Excitation Fluorescence Bandpass Filter; t=3mm 608-648nm
This is the 628-40 EX, a 25 mm diameter mounted excitation fluorescence bandpass filter, with a thickness of 3mm, specifically designed for the wavelength of 628nm. The filter is sourced from the reputable optical components vendor, Iridian Spectral Technologies.
The filter is of the bandpass type, which means it allows a specific range of wavelengths to pass through while blocking others. In this case, the cut-on wavelength is 608nm, and the cut-off wavelength is 648nm. This means the filter will pass wavelengths between these two values, making it ideal for applications that require narrow-band light.
The 628-40 EX filter is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter is coated on both the front and back with the Iridian-specific coating, IRI 628-40-ex, which enhances its performance and durability.
The filter's shape is that of a thin lens, which is designed to minimize optical aberrations and ensure the highest quality light transmission. This makes the 628-40 EX an excellent choice for applications that require high-precision optical filtering.
According to the vendor's website, the filter is currently in stock, and you can find more information about it, including its catalog number and detailed specifications, at https://www.iridian.ca/product/628-40-ex/.
