14-526 50 x 50 mm SCHOTT RG715 Black Colored Glass Longpass Filter 715nm

The 14-526 is a 50 x 50 mm SCHOTT RG715 Black Colored Glass Longpass Filter, designed to transmit light with wavelengths longer than 715nm while blocking shorter wavelengths. This filter is sourced from Edmund Optics and is available for purchase on their website.

The filter is made of color glass, a type of optical filter that uses dyes or pigments to absorb unwanted wavelengths. This particular filter is made from SCHOTT glass, a renowned German manufacturer known for producing high-quality optical glass. The RG715 designation indicates that this filter has a cut-on wavelength of 715nm, meaning it begins to transmit light at this wavelength and above.

The filter has a rectangular shape, with a width of 50mm and a height of 50mm, making it suitable for use in a variety of optical systems. It has a thickness of 1mm, which is considered thin in the context of optical elements. This thinness can be beneficial in applications where space is limited or weight is a concern.

The filter's coating is another crucial aspect. Both the front and back surfaces of the filter are coated with "edm 14-526", a coating that likely enhances the filter's performance by reducing reflections and increasing transmission. The exact nature of this coating is not specified in the item data, but it is safe to assume that it is designed to work optimally with the filter's glass type and intended use.

In terms of physical data, the filter's cut-on wavelength is 715nm, and there is no specified cut-off wavelength, indicating that it continues to transmit light at wavelengths longer than 715nm. The filter's geometry includes its width, height, and thickness, as previously mentioned.
