Off-Axis Paraboloids Enhance Laser Power Density

Enhance Laser Power DensityOff-axis paraboloids offer the advantage of an unobstructed aperture and access to the focal plane. In addition, due to their completely achromatic performance, they are especially suitable for broadband or multiple wavelength applications. Continue…

Hyperbolic Mirrors for Deep Space Observation

Hyperbolic Mirrors for Deep Space Observation

Optical Surfaces Ltd. is a leading international manufacturer of hyperbolic mirrors for deep space observation telescopes and earth observation satellites. A hyperbolic mirror is the optical component of choice for precisely and accurately focusing light in a telescope from one focal point to the other focal point. Hyperbolic mirrors are used in a telescope design to correct certain distortions caused by an extremely fast f-ratio design. A hyperbolic secondary mirror is used ...

Demanding Telescope Spectrograph Optics

Benefiting from a unique facility, where temperatures remain constant year-round and vibration is practically non-existent, Optical Surfaces Ltd is able to routinely produce and test demanding telescope spectrograph optics (aspheres, flats, lenses, mirrors and prisms) that stretch the limits of conventional optical fabrication techniques. Using a spectrograph, researchers are able to study the chemical and physical conditions that exist through a cross-section of space. Combined with a land or space-based telescope ...

Large Prisms for Demanding Spectroscopic Applications

Optical Surfaces Ltd. is a leading manufacturer of large, high quality prisms for spectroscopic, surveying and telescope applications. Prisms are solid optics that are ground and polished into geometrical and optically significant shapes where the angle, position, and number of surfaces help define the type and function. Spectroscopic applications typically demand that prisms must be manufactured with very strict tolerances and accuracies. Due to the variability in shape, size and the number ...
