FB1520-12 Dia:1 in Bandpass Filter; CWL=1520 +-2nm; FWHM=12 +-2.4nm

The FB1520-12 is a high-quality Bandpass Filter, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed with a circular base shape, made from soda lime ru clear material, and features a diameter of 25.4mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications.

The FB1520-12 filter is specifically designed to operate at a central wavelength (CWL) of 1520nm, with a full width at half maximum (FWHM) of 12nm +-2.4nm. This ensures a tight passband, making it ideal for applications that require precise wavelength selection. The filter's cut-on wavelength is 1514nm, and the cut-off wavelength is 1526nm, providing a narrow passband that effectively rejects out-of-band light.

The filter's coating is a crucial component of its design. Both the front and back surfaces of the filter are coated with the same coating, denoted as 'tho fb1520-12'. This coating is specifically designed to enhance the filter's performance, ensuring high transmission and low reflection across the passband.

The FB1520-12 filter is available in a Thin Lens shape, which provides excellent optical performance and ease of integration into optical systems. The filter's current status is 'in stock', and more information about this product can be found on Thorlabs' official website.
