Visible/IR And Reflector Lamps
Visible/Infrared Lamps
Our T 3/4 and T-1 Visible/Infrared lamps are designed for applications requiring wide spectrum emis- sion, such as gas sensing and detection. These lamps are made with a rugged, compact CC-6 filament that concentrates infrared energy into a small point. The thin glass envelope results in minimum infrared absorption. Peak energy of these lamps occurs at 1.4 microns and extends beyond 4.0 microns. The visible/infrared lamps have been designed for long life and can be supplied with standard wire leads or a bi-pin base.
Reflector Lamps
Reflector lamps are an excellent choice when lighting applications require directional control of emitted light. The use of a reflector can increase light output two to five times. Our MR11 and MR16 dichroic reflector lamps serve to collect the visible light and focus it forward into an intense pattern.The dichroic reflector allows most of the light with wavelengths longer than 700 nanometers to pass through the reflector. This effectively selects only the visible portion of the light to form the beam. These lamps are recommended for fiber optic illumination, machine vision, and other optical systems requiring high output.
Our aluminum reflector assemblies are available in sizes ranging from MR3 to MR8. These assem- blies produce a small, uniform, high intensity light spot and are ideal for use in fiber optic illumination and gas sensing applications. Unlike the dichroic reflector, the aluminum reflector projects all light, including the UV and the infrared portions. Many of these assemblies are available with a threaded lamp holder allowing for easy manipulation of the light beam and focal distance. We can also permanently bond the lamps into the reflector to create a prefocused spot.
Gold Coated Reflector Lamps
The dichroic reflector lamps and the aluminum reflectors mentioned above can also be supplied with a gold coating. This layer of gold provides for increased emission in the infrared (see figure below). Applications of gold coated reflectors include open field IR gas detection, local infrared heating, and remote testing of flame detectors.
