FB5068-100 Dia. 25 mm IR Bandpass Filter; CWL=5.068 μm; FWHM=100nm

The FB5068-100 is a high-quality Bandpass Filter, sourced from the reputable vendor Thorlabs. This particular model boasts a circular shape, with a diameter of 25 mm and a thickness of 1 mm, making it a versatile choice for various optical applications.

The filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths. The central wavelength (CWL) of this filter is 5.068 μm, and it has a full width at half maximum (FWHM) of 100 nm. This means it allows light to pass through if its wavelength is close to 5.068 μm, with a tolerance of 100 nm on either side.

The FB5068-100 is made from sapphire ow mal-1972, a material known for its excellent optical properties. The filter is coated on both the front and back with the "tho fb5068-100" coating, which further enhances its performance.

This filter is designed to be used in a thin lens configuration, making it compatible with a wide range of optical systems. The filter's current status is "in stock", according to Thorlabs' website, and it can be purchased directly from their site using the provided weblink.
