Shortwave Infrared wavelength band offers a unique imaging advantages over visible and other thermal bands. So it is quietly earning a growing place in industrial machine vision for quality inspection and in military applications. SWIR lenses are utilized where other detectors or cameras are not sensitive enough for the finite detail recognition. At Hyperion Optics, we have developed a series of SWIR lenses to meet the latest advancement of SWIR technology. Our design is for high-resolution operation at low light level. It also offers a superior image quality, better transmission, and performance. Our SWIR lenses function in the wavelengths of 900nm-1700nm / 700nm-3400nm with the detector size up to 20mm diagonal and pixel size of 15-50μm.
Apart from off-the-shelf SWIR optics, Hyperion Optics offers custom SWIR system design, for glass selection, We offer Schott / OHARA based glass choices and has a wide range of Schott and OHARA molded substrates inventory in various diameter and CT which assist us to greatly lower down your investment on glass materials. further to minimize your investment, we offer actual tested refractive index and dispersion testing on CDGM and NHG material equivalents through 0.7μm to 2.5μm for a better performance optimizing at the lowest price. We also can disclose our internal material refractive index and dispersion test data (with correspondent materials stock) for designers to develop your own SWIR system upon request. Glass witness samples can be provided free of charge for index and dispersion testing on customers'side too.
Please talk to one of our experienced optical designers to know how it works.
For custom SWIR design, we encourage the customer to choose materials from NHG for cost-wise decision if your budgetary is tight. Please contact us for latest NHG glass catalog update, since NHG is keeping releasing new refractive index and dispersion data through VIS to 2500nm periodically.
Our custom SWIR prototyping project starts from 2 to 5 sets. For applications such as hyperspectral CCD spectrometer, we also work with customer’s design as a build to print, further to provide assembly and test service. (Including wavefront error, MTF, Transmission etc.)
Off-The-Shelf SWIR Lenses
If you need further SWIR optics technical support please contact us. We also provide LWIR lens for thermal imaging surveillance applications.
The IR lens adopted the advanced technologies such as the latest optical design methods, special optical glass materials and special ferry films and materials, eliminating the focal plane deviation of visible light and infrared light.
The MWIR lens uses special optical glass materials as well as special ferry films and materials. The special optical glass material solves the problem of infrared corresponding clear imaging so that the light from the visible region to the infrared region can be obtained in the same focal plane position to achieve a clear image. Special crossing technology allows the infrared light to penetrate as far as possible. The multi-layer coating can also minimize the occurrence of ghost and flash in the backlight condition, and the high contrast quality can be obtained even under the bad conditions such as backlighting.
IR lens has a wide range of applications, which can be used as infrared for a special purpose or as a normal lens. In other words, the MWIR lens can be used with the regular color camera, black and white camera and the day and night conversion camera. Black and white cameras have no infrared cut-off, but the spectrum of sunlight also contains infrared light, so even in daylight, the image of a black-and-white camera is subject to infra-red interference. Therefore, the MWIR lens can effectively improve the image quality.
