FL532-3 Dia:1 in Laser Line Filter; CWL=532 +-0.6nm; FWHM=3 +-0.6nm

The FL532-3 is a bandpass filter from Thorlabs, designed with a center wavelength of 532 nanometers and a full width at half maximum (FWHM) of 3 +-0.6 nanometers. This filter is specifically engineered for use with laser line applications, offering a high transmission rate within the specified wavelength range while effectively blocking out unwanted light.

The filter is circular in shape, with a diameter of 1 inch (25.4 millimeters) and a thickness of 3.5 millimeters, making it compatible with a wide range of optical systems. It is constructed from soda lime ru clear material, ensuring durability and reliability in various environments.

The FL532-3 features anti-reflection coatings on both the front and back surfaces, designated as 'tho fl532-3'. These coatings are designed to minimize surface reflections, thereby enhancing the overall transmission efficiency of the filter. The cut-on wavelength is 530.5 nanometers, and the cut-off wavelength is 533.5 nanometers, further emphasizing the filter's narrow bandpass characteristics.
