We make all kinds of lenses up to Ø200mm. Also available with anti-reflection coatings. Lenses can be also be mounted as required.
Windows are optical elements having where both the surfaces are plane in nature. We can manufacture windows up to 200mm in size. Windows can be coated with anti-reflection coating which increases the transmission. They can be of general grade, just being optically polished or precision grade, with control on the parallelism and flatness. We can manufacture windows with parallelism of less than 5 seconds between the surfaces and with flatness up to lambda/10 depending on the size and thickness. We also supply windows as thin as 0.1mm.
Prisms play an important part in any optical system. Their main function is to deviate the beam of light in a different direction. They also considerably shorten the light path of an optical system and can invert and revert images, the reason for their being used in binoculars. They can break up the light into its constituent colors. They are available with anti-reflection coatings as well as other coatings as required. Prisms can be made to high degrees of angular accuracy.
Mirrors are used for reflecting the light in optical systems. They are can be designed for either normal or oblique angles of incidence and can be partial reflectors or high reflectors. They can have one curved surface or both plane surfaces also. Telescope mirrors are examples of aluminum coated mirrors. Dielectric coated mirrors can be used with lasers and a variety of applications.
Beam splitters partially reflect / transmit the incident light. They are normally used at 45 degrees incidence. They split the laser beam in required R/T ratio. They can either be in plate form (like a window) or in cube form. Cube beam splitters have two right angled prisms of similar material cemented together. One of the prisms has the beam splitter coating on its hypotenuse.
Filters are used to "filter" out light, i.e. to separate out wavelengths. They can be similar to windows in size and shape. We manufacture filters of various types.
We make Optical flats up to lambda/10 accuracy from Pyrex or Fused Silica.
We can manufacture laser optics with high damage threshold coatings as per customers requirements.
Optical assemblies are an integral part of any optical system. We have a fully equipped metal working shop including a CNC lathe machine from Hardinge, USA to give all kinds of optical mountings for our optics. We can make assemblies as per your specifications. Assemblies are done on Class 100 workstations in Class 10,000 clean room.
