67-301 50 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=5mm 1175nm
The 67-301 is a Longpass Filter, a type of optical filter that transmits wavelengths longer than a specified value, while blocking shorter wavelengths. This particular model has a diameter of 50 mm and a thickness of 5 mm, making it suitable for a wide range of optical applications.
The filter is manufactured by Edmund Optics, a leading supplier of optical components, and is available for purchase through their website. The product page (https://www.edmundoptics.com/p/1175nm-50mm-diameter-od-2-longpass-filter/21809/) indicates that the filter is currently in stock, ensuring quick delivery for those who need it.
The 67-301 features a cut-on wavelength of 1175 nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength, which is the point at which the filter starts to block light, is 0 nm. This makes the filter ideal for applications that require the transmission of infrared light.
The filter is coated with EDM 67-295 on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring it maintains its optical properties over time.
The filter's shape is described as Thin Lens, indicating it has been designed to focus light. This could be useful in applications where light needs to be concentrated onto a specific point or area.
