Spherical Mirror (Convex)
A Convex Mirror or a diverging mirror is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards; therefore they are not used to focus light. Such mirrors always form a virtual image,
As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror. The image is smaller than the object, but gets larger as the object approaches the mirror.
Precision Spherical Mirrors:
Precision Spherical Mirrors are designed for research and technical OEM applications in the UV, visible or IR ranges. All are ground, polished. Each size is available with various reflective coatings. These mirrors have a Surface Accuracy from λ/4 to λ /10 and Sizes vary up to 150mm.
We can supply large dimension Mirrors Spherical or Parabolic from 300mm to 1000mm with a thickness of 50mm to 125mm with Surface accuracy of λ /4.
These mirrors are aluminized on the surface nearest the incident light. Energy loss is minimized because light does not pass through the glass substrate. We have shapes available in circle, square and rectangle. Custom sizes are available for volume OEM requirements.
Cold & Hot Mirror
Cold Mirrors reflect visible wavelength and Transmits IR hence it can be used to build projection systems without worrying about heat build-up with our 0° angle of incidence cold mirrors. The multi-layer dielectric coating on these glass mirrors reflects 90% of visible light while allowing better than 80% transmission of IR waves. Cold mirrors are ideal for illumination systems where high temperature lighting is not desired. Mirror will function satisfactorily and will not be damaged by exposure to an ambient temperature of -50°F to +450°F.
- Reflect IR
- Transmit Visible wavelength
Available for an angle of incidence of 0°, these heat reflecting mirrors can be used in a variety of optical systems where heat build-up is a concern. Applied mainly in projection and illumination systems, the multi-layer dielectric coating on the mirrors reflects harmful infrared radiation (heat), while allowing visible light to pass through. Hot mirrors make an intelligent addition to optical systems that could otherwise be damaged by excessive heat.
Note: Whenever using high power illumination, forced air cooling is recommended.
