33-145 25 mm Diameter Infrared (IR) Bandpass Filter; t=1 mm 10600nm

The 33-145 is a 25 mm diameter Infrared (IR) Bandpass Filter, with a thickness of 1 mm, designed to transmit light in the 10600nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.

The filter is designed with a Base Shape of Circular and a Sub Type of Bandpass Filter, making it ideal for applications that require the selection of specific wavelengths while rejecting others. The 33-145 features a Germanium Burnett material ID, which is known for its excellent transmission properties in the infrared spectrum.

The physical data of the filter includes a cut-on wavelength of 9850 and a cut-off wavelength of 11350, with a center wavelength (CWL) of 10600. This means that the filter will begin to transmit light at 9850nm and stop transmitting at 11350nm, with the highest transmission efficiency at 10600nm.

The 33-145 is coated with EDM 33-144 on both the front and back surfaces, which enhances its performance and durability. The filter has a Thin Lens shape, making it suitable for use in optical systems where a thin, lightweight element is required.
