FB3750-500 Dia. 1 in IR Bandpass Filter; CWL=3.75 µm; FWHM=500nm

The FB3750-500 is a high-quality bandpass filter developed by Thorlabs, a leading vendor in the optical industry. This filter is specifically designed for infrared (IR) applications, with a central wavelength (CWL) of 3.75 µm and a full width at half maximum (FWHM) of 500nm.

The filter is made from sapphire ow mal-1972, a material known for its exceptional optical properties and durability. It features a circular base shape, with a diameter of 1 inch (25.4mm) and a thickness of 3mm, making it compatible with a wide range of optical systems.

The FB3750-500 is designed with a cut-on wavelength of 3500 and a cut-off wavelength of 4000, providing a narrow and precise passband for IR applications. The filter's coating, applied to both the front and back surfaces, enhances its performance and durability. The coating is specifically designed for the FB3750-500, ensuring optimal performance and longevity.

The filter's shape is that of a thin lens, which not only provides superior optical performance but also allows for easy integration into existing optical systems. The filter is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
