FB3330-150 Dia. 25 mm IR Bandpass Filter; CWL=3.33 µm; FWHM=150nm

The FB3330-150 is a high-quality Bandpass Filter, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed with a circular shape, featuring a diameter of 25 mm and a thickness of 1 mm, making it suitable for a wide range of optical applications.

The filter is constructed from UVFS MAL-1965, a material known for its excellent optical properties. It is specifically designed to pass light in the infrared (IR) region of the spectrum, with a central wavelength (CWL) of 3.33 µm and a full width at half maximum (FWHM) of 150 nm. This precise wavelength range ensures optimal performance in specific applications where such a spectral response is required.

The FB3330-150 is coated on both the front and back surfaces with Thorlabs' proprietary coating, denoted as 'tho fb3330-150'. This coating enhances the filter's performance by controlling the reflection and transmission of light at various wavelengths. The filter's shape is designed in a Thin Lens format, which can be beneficial in certain optical system configurations.
