High performance tube collimators
Based on off-axis paraboloids using zero expansion glass ceramic, and constructed in aluminium with matt black internal walls, the units can be supplied athermalised
The new range of tube collimators from Optical Surfaces is based on its well known off-axis paraboloids using zero expansion glass ceramic to ensure long term stability Constructed in aluminium with matt black internal walls, the units can be supplied athermalised to suit a wide range of conditions

High performance tube collimators
The new range of tube collimators from Optical Surfaces is based on its off-axis paraboloids using zero expansion glass ceramic to ensure long term stability
All optics within the tube collimators come pre-aligned in stress-free mounts.
The combined optical performance is better than lambda/5 p-v at 633nm wavefront in the field centre.
To facilitate ease of use each of the collimator's three feet is adjustable by +/-10mm for centre height positioning.
Unlike other collimator solutions, the new Optical Surfaces range is transportable from site to site while maintaining alignment.
As standard, all optics with the tube collimators come coated with aluminium and magnesium fluoride, providing achromatic performance at any wavelength from the ultra-violet through the visible into the infrared.
Alternative specialised coatings such as gold, silver, and dielectric are available.
Each system has an output port datum plane giving a defined distance to the focus.
Where a highly stabilised focal plane is required the collimator optics may be invar tied.
All collimators provide a 20mm field ensuring compatibility with standard black bodies.
Customised systems can be supplied with larger field sizes, different output interfaces and platforms.
Other options include reticle holders, lamphouses and black bodies.
Optical Surfaces facilities are approved to ISO9001:2000 and collimators are supplied with test interferograms and analysis showing wavefront accuracy and measured data including focal length and working distance.
