46-388 50 x 50 mm Extended Hot Mirror 0 deg AOI 425-1600nm

The 46-388 is a 50 x 50 mm Extended Hot Mirror, designed for use in optical systems that require the separation of visible and infrared light. Sourced from Edmund Optics, this filter is part of their extensive catalog of optical elements, and it is currently in stock.

The filter is made from borofloat33, a borosilicate glass known for its excellent thermal shock resistance and low thermal expansion coefficient. This makes it an ideal choice for applications that involve rapid temperature changes. The filter has a thickness of 3.3 mm, providing structural rigidity and minimizing the risk of deformation.

The 46-388 features a hot mirror coating on both the front and back surfaces, identified as edm 47-304. This coating is designed to reflect infrared light while transmitting visible light. The mirror has a wavelength of 588 nm, which falls within the yellow-green region of the visible spectrum. This makes it suitable for applications that involve yellow, green, or blue light.

The filter is rectangular in shape, with a width of 50 mm and a height of 50 mm. This size is commonly used in optical systems that require a compact, square filter. The filter's shape is classified as a Thin Lens, indicating that it has been designed to minimize optical aberrations and distortions.
