Reflector light bulb types8/12/2023 ![]() ![]() Gold provides for increased emission in the infrared. Silver often requires a second coating to prevent tarnish. Silver is more expensive than aluminum but offers a slight improvement in the NIR region. Silver coating is often used to increase the NIR output in the 700 - 1100 nm range. Aluminum coating is less expensive than silver and gold and slightly less effective in many regions of the IR. Some MR11 and MR16 Dichroic lamps may be available with aluminum coating to allow the light above 700 nm to be included in the beam. ![]() Coatings are typically used to increase the IR output of a reflector assembly.Īluminum reflectors in sizes MR3 - MR8 are typically machined and require no coatings. Most ILT reflectors and reflector assemblies can be coated in aluminum, gold or silver. Threaded Machined Aluminum reflectors can be combined with a threaded holder to allow easy manipulation of the light beam and focal distance, or the lamp can be permanently bonded to the reflector to create a pre-focused spot based on customer requirements.Ĭlick here to go to our reference drawing page Larger/custom sizes are available up to 76 mm diameter. Machined aluminum reflectors are available in parabolic and ellipsoidal models. Aluminum reflectors project all light forward including the UV and the infrared portions. These assemblies produce a small, uniform, high intensity light spot and are ideal for use in fiber optic illumination and gas sensing applications. Machined Aluminum reflector assemblies are available in standard sizes ranging from 9.5mm to 25mm diameter (MR3-MR8). Unlike the dichroic reflector, the aluminum reflector projects all light forward, including the UV and the infrared portions. Parabolic reflectors are available in sizes MR3 to MR8. ![]() Parabolic reflectors will project the light into a parallel beam. These lamps are recommended for fiber optic illumination, machine vision, and other optical systems requiring high output. Dichroic reflectors are available in MR11 and MR16 sizes. Ellipsoidal reflectors are available in sizes MR3-MR16.ĭichroic reflectors allow most of the IR light (above 700 nm) to pass through the reflector and use the visible portion of the light to form the beam. The use of a reflector can increase light output two to five times.Įllipsoidal reflectors collect the lamp output (UV, VIS and IR Light)and focus it forward into an intense pattern at a specified distance. ILT offers a variety of reflector sizes, types and finishes ranging from MR3 (9.5 mm Dia.) to MR16 (50 mm Dia.) Reflector assemblies are an excellent choice when lighting applications require directional control of emitted light.
