Prinz Optics coats glass for measuring, displays, tempering, lighting and many other applications. The glass is used in industry and science as optical filters and reflectors – for example, cold light or splitter mirrors. Thanks to our know-how and appropriate technologies, we can solve your special lighting problems.
Anti-reflective glass surfaces are essential in laser and measurement technology. Broadband antireflective glass is used for display cabinets and sight glasses. Our semi-transparent mirrors / beam splitters for 3D visualisation and teleprompters are used in image processing.
In medical technology, our heat reflection filters are used whenever the thermal load needs to be reduced in illuminated areas. Defined light properties in surgical lighting and lighting devices for microscopy and endoscopy are achieved using our conversion filters.
UV and colour filters are used in irradiation technology; anti-reflective glass covers are used in laser technology. Certified production processes ensure that the safety requirements for medical technology are fulfilled.
Customised filter for use in test devices for light resistance
Nearly all powerful light sources emit superfluous or unwanted frequencies in addition to the required light that subject the illuminated objects to heat. Our IR filter, based on the substrate BOROFLOAT, can be used to remove the unwanted rays in the near-infrared region (NIR) from the light beam:
FILTER TYPE | spectral position of Reflection | |
---|---|---|
IR2 | 870 - 950 nm | 17 kB |
IR3 | 850 - 900 nm | 17 kB |
IR4 | 800 - 850 nm Filter with higher UV transmission / Sun simulation | 17 kB |
IR5 | 800 - 900 nm | 17 kB |
IR6 | 1000 - 1100 nm | 17 kB |
IR7 | 850 - 900 nm | 17 kB |
(maximum filter dimensions 1,080 x 800 mm)
UV light is a problem when it causes damage, e.g. bleaches colours, makes plastics brittle, destroys paintings, provokes skin cancer, etc. It can be reliably blocked using our filters:
Filter type | Edge position | |
---|---|---|
UB2-AR | 350 ±10 nm very high transmission in the visible area | 17 kB |
UB4 | 400 ±10 nm | 17 kB |
Filters with blue suppression for discharge lamps prevent, that insects are irresistibly attracted by the night lighting:
Filter type | Edge position | |
---|---|---|
UB4-420 | 400 ±10 nm | 17 kB |
UB4-440 | 45 kB | |
FM Yellow | 16 kB |
UV light-specific, these types can be used for drying paints and glues:
Filter type | Reflection maximum | |
---|---|---|
UR 350-0 | Rmax >= 96 % at 350 nm also available for use below 45° | 17 kB |
UR 260-0 | Rmax >= 93 % at 350 nm | 17 kB |
URBB | Rmax >= 70 % at 250-350 nm Broadband reflection | 17 kB |
Another way to reduce the heat received by illuminated objects is to use this filter to reflect the visible light (VIS) while letting through thermal radiation (IR), BOROFLOAT coated:
Filter type | Angle of incidence | Reflection maximum | |
---|---|---|---|
KR3 | Angle of incidence 0° - 45° | Rmax >= 90% at 420-650 nm | 19 kB |
Filters with lower reflection/partial reflection or neutral reflection in the VIS are suitable for decorative purposes:
Filter type | Reflection maximum | |
---|---|---|
M3 | Rmax >= 70% at 450 - 600 nm | 16 kB |
M1 | Rmax >= 40% at 400 - 650 nm | 16 kB |
We offer anti-reflective coatings on all common substrates in the visible region (VIS 380 - 780 nm) and near-infrared region (NIR 780 - 1,550 nm). They are available as either AR2 for individual wavelengths or as AR4 for wavelength ranges (broadband AR). AR filters are used for displays, for glass cabinets to reduce reflection, and to increase the transmission in protective glass for high-power lamps, diodes and lasers. It is also available for anti-reflection on pipes (6 mm to 300 mm in diameter).
Filter type | Reflection maximum | |
---|---|---|
AR2-550 | Reflection < 0.5% at 550 nm | 12 kB |
AR2-1064 | Reflection < 0.5% at the selected wavelength 1064 nm | 12 kB |
AR4 | Reflection < 1% for λ= 450 nm - 650 nm | 12 kB |
AR4-850 | Reflection < 1% for λ= 650 nm - 950 nm | 12 kB |
AR4 350-420 | Antireflection in the near-UV range |
In driving and flight simulators and teleprompters, light needs to be split into transmission and reflection as colour neutral (achromatic). The reverse side is anti-reflective to prevent double images. These filter types are available:
Filter type | Transmission | Reflection | |
---|---|---|---|
AT80 | 80±5% | 20±5% | 16 kB |
AT70 | 70±5% | 30±5% | 16 kB |
AT60 | 60±5% | 40±5% | 16 kB |
AT50 | 50±5% | 50±5% | 16 kB |
AT40 | 40±5% | 60±5% | 16 kB |
The filter AT40 (without anti-reflection on the reverse side) can be used for colour-neutral light attenuation.
