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…

Off-Axis Parabolic Mirrors for Imaging Applications

Off-Axis Parabolic Mirrors for Imaging Applications

Optical Surfaces Ltd is a leading international manufacturer of Off-Axis Parabolic Mirrors (OAPs) for demanding imaging applications. Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP's offer the ability to focus collimated light without introducing spherical aberration. Additionally, unlike ...

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 ...
