The FL632.8-1 is a circular bandpass filter with a diameter of 1 inch, sourced from the reputable vendor Thorlabs. This filter is designed to transmit light at a central wavelength (CWL) of 632 nanometers, with a full width at half maximum (FWHM) of 1 +-0.2 nanometers.
The filter is made of soda lime ru clear material, and it features a thin lens shape. It has a thickness of 3.5 millimeters and a cut-on wavelength of 631.5 nanometers, as well as a cut-off wavelength of 632.5 nanometers.
The front and back of the filter are coated with tho fl632.8-1, providing optimal performance for its intended application. The filter's weblink status is valid and it is currently in stock, according to the vendor's website.
This filter is ideal for applications that require precise wavelength selection and high transmission in the red region of the spectrum. It is commonly used in laser systems, interferometry, and other applications where monochromatic light is essential.
