FLH05532-4 Premium Bandpass Filter; Dia:12.5 mm; CWL=532nm; FWHM=4nm

The FLH05532-4 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter features a circular shape with a diameter of 12.5 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems.

The filter's primary function is to allow light transmission within a specific wavelength range, while blocking unwanted wavelengths. In this case, the central wavelength (CWL) is 532 nm, and the full width at half maximum (FWHM) is 4 nm. This means that the filter is designed to transmit light most efficiently at 532 nm, with a tolerance of ±2 nm. The FWHM specification indicates the bandwidth of the filter at half the maximum transmission, providing a measure of the filter's selectivity.

The FLH05532-4 filter is coated with Tho FLH532-4 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.

This filter is part of the UVFS MAL-1965 material category, which suggests its suitability for use in ultraviolet, visible, and short-wave infrared applications. The filter's thin lens shape further expands its potential applications, making it a versatile component in various optical setups.
