84-075 25 mm Dia. Infrared (IR) Bandpass Filter; t=1 mm 5300nm

The 84-075 is a 25 mm diameter Infrared (IR) Bandpass Filter, with a thickness of 1 mm, specifically designed to transmit light in the 5300nm wavelength range. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website.

The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the 84-075 is designed to pass light in the 5300nm range, making it ideal for applications that require the use of specific IR wavelengths.

The filter is made from Aluminum Oxide (Al2O3), with the specific mal-1972-n-o variant used. This material is known for its excellent optical properties, making it a popular choice for various optical applications.

The geometry of the filter includes a diameter of 25 mm and a thickness of 1 mm. The diameter is a crucial factor as it determines the size of the beam that can pass through the filter. The thickness, on the other hand, can affect the filter's performance, especially in applications that require high precision.

The physical data of the filter includes a cut-on wavelength of 5090nm and a cut-off wavelength of 5510nm. The cut-on wavelength is the shortest wavelength that the filter will allow to pass, while the cut-off wavelength is the longest. The central wavelength (CWL) of the filter is 5300nm, which is the wavelength at which the filter has its maximum transmittance.

The filter is coated on both the front and back with the EDM 84-075 coating. This coating is designed to enhance the filter's performance and durability, ensuring that it maintains its optical properties even after prolonged use.

The shape of the filter is a Thin Lens, which is a type of optical element that focuses light by bending it. This shape can be beneficial in applications that require the focusing of light, such as in imaging systems.
