Infrared Viewers/ Ultraviolet Viewers

High performance infrared monocular viewers are designed to observe radiation emitted by infrared sources. They can be used to observe indirect radiation of IR LED's and diode lasers, Nd:YAG, Ti:Sapphire, Cr:Forsterite, dye lasers and other laser sources. IR viewers are ideal for applications involving the alignment of infrared laser beams and of optical components in near-infrared systems.
The light weight, compact monocular may be used as a hand-held or facemask mounted for hands free operation.

Ultraviolet viewers are designed to observe radiation emitted by UV sources.


Laser alignment and safety
Lasers, which can be observed with IR-viewers:
GaAs laser diodes @800 - 950nm, GaAlAs @1350nm, Nd:YAG @ 1064nm,
Ti:Sapphire @ 690 - 1000nm, Li:F2 @1090 - 1270nm, Cr: Forsterite @ 1150 - 1350nm etc.
Near IR viewers are extremely important for locating stray beam reflections that may cause eye damage or injury.

Semiconductor inspection

New Application! From Optics.Org: Infrared light probes varicose veins.
An infrared digital imaging system will be used to compare three varicose vein treatments.

New Application! From Optics.Org: Infrared light detects tooth decay.
A dentist’s toolkit for detecting tooth decay could soon include an infrared-imaging system.
Shining infrared light with a wavelength of 1310 nm through a tooth is an effective way to spot early decay, according to a team from the University of California at San Francisco, US.

Thermal imaging
The IR-viewers can be used to image the thermal radiation of objects above 600°C (such as kilns, furnaces or solder pots). Objects in this temperature range (and hotter) emit enough infrared radiation in the 0.8-1.5 micron wavelength range to be imaged.

Night vision
Invisible near-infrared illuminator is used as a light source for night vision applications.

Typical Spectral Response
(sensitivity versus wavelength)

Minimum power densities required to view an infrared laser beam from a distance of one meter:
mW/cm2 for 1.06mm
mW/cm2 for 1.3mm

Standard IR viewers have spectral response up to 1300nm. IR viewers with extended spectral range are available: models 1700 (with sensitivity up to 1700nm) and model 2000 (with sensitivity up to 2000nm).
