64-659 50 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=5mm 1075nm

The 64-659 is a Shortpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This filter boasts a 50 mm diameter and a thickness of 5 mm, making it suitable for a wide range of applications. The Shortpass Filter type implies that it allows wavelengths shorter than a specified value to pass through while blocking longer wavelengths. In this case, the cut-off wavelength is 1075 nm.

The filter's geometry is defined by its diameter and thickness. The 50 mm diameter is a common size for optical components, offering a good balance between size and light-gathering capability. The 5 mm thickness, referred to as 't', is relatively thin, which can be beneficial in reducing weight and potential optical aberrations.

The filter's physical data includes a cut-on wavelength of 0 nm and a cut-off wavelength of 1075 nm. This means that it begins to transmit light at 0 nm and stops transmitting at 1075 nm. The coating on both the front and back surfaces of the filter is 'edm 64-645', which is likely a specific coating type or number used by Edmund Optics.

The filter's shape is described as 'Thin Lens', suggesting that it may have some lens-like properties, such as a curved surface, although this is not explicitly stated in the provided data.
