Visible Filters

Together with our supplier Vortex, we are able to design and manufacture custom visible filters with short lead-times for many applications. All Vortex filters are sputtered, meaning they are highly durable. We can provide all common types of filter, like Long Wave Pass (LWP), Short Wave Pass (SWP), Wide Band Pass (WBP) and Narrow Band Pass (NBP).

Some Examples:

• Visible Long Wave Pass Filter for blocking lower visible wavelengths (e.g. below 530 nm). Applications include fluorescence, medical systems, order sorting in spectrometers and scientific instruments.
• Visible Short Wave Pass Filter for blocking longer wavelengths (e.g. above 730 nm) and transmitting short wavebands. Applications include thermal management (Hot Mirrors) in systems and shortening the ranges of sensitivity of detectors.
• Visible Wide Band Pass Filter used to block a higher and lower wave band and allow a band (e.g. 550 nm to 600 nm) to transmit. A typical application is to isolate a working band in visible systems using Silicon photodiode detectors or visible cameras.
• Visible Narrow Band Pass Filter typically used to isolate a narrow wavelength range (e.g. around 530 nm) for use in scientific analysis or LED tidying.
• Steep Edge 45 Deg LWP Filter for separation of colors at 45° angle of incidence – for example blue reflected, orange/red transmitted.
• Extended Hot Mirror for 45 Deg Angle of Incidence – a type of SWP filter can be used for an application, where the requirement is to reflect the heat of the near infra-red and allow some visible transmission.

We are happy to provide a unique visible filter – designed, specified and manufactured to your application’s requirements. Contact the AMS Technologies filter experts today to discuss your customized visible filter solution!
