FL632.8-3 Dia:1 in Laser Line Filter; CWL=632 +-0.6nm; FWHM=3 +-0.6nm
The FL632.8-3 is a circular bandpass filter with a diameter of 1 inch, designed for use with laser line applications. This filter is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The filter is made from soda lime ru clear material, ensuring durability and clarity.
The filter is specifically designed for use with a central wavelength (CWL) of 632 nanometers, with a full width at half maximum (FWHM) of 3 nanometers. The CWL is the wavelength at which the filter has its maximum transmittance, while the FWHM is a measure of the filter's bandwidth. This makes the FL632.8-3 ideal for applications that require a narrow bandwidth around the 632 nanometer wavelength.
The filter has a cut-on wavelength of 630.5 nanometers and a cut-off wavelength of 633.5 nanometers. This means that the filter begins to transmit light at 630.5 nanometers and stops transmitting light at 633.5 nanometers. The filter's coating, applied to both the front and back surfaces, is designated as 'tho fl632.8-3'. This coating enhances the filter's performance and durability.
The FL632.8-3 has a thickness of 3.5 millimeters and features a thin lens shape. This shape allows for easy integration into optical systems. The filter is currently in stock and available for purchase, as indicated by its valid weblink status.
