Using proprietary manufacturing techniques and benefiting from extremely stable manufacturing facilities, Optical Surfaces Ltd have established themselves as a leading supplier of fast axis focusing parabolic mirrors for high power laser experiments.
175 mm diameter, F0.8 on-axis parabolic mirror with surface accuracy better than λ/10 PV and scratch/dig smoothness of 20/10. Manufactured for the Central Laser Facility (CLF) at STFC’s Rutherford Appleton Laboratory (RAL), the mirror has a UV silver coating that provides >98% reflectance over the wavelength range 300-800 nm.

The inherent on-axis parabolic mirror allows for a higher f-number (<0.7) than off-axis designs, allowing more laser energy to be focused on the test target. Parabolic mirrors are also easier to use, as on-axis alignment is generally less critical.
Generations of customers have been purchasing on-axis parabolic mirrors from Optical Surfaces Ltd. The company has a 50+ year heritage of manufacturing optics for large telescopes over one meter in diameter for many prestigious clients, including the Royal Observatory Greenwich.
On-axis parabolic mirrors perform completely free of chromatic aberration, making them suitable for both broadband and multi-wavelength laser applications. Manufactured from materials including glass, ceramic and silica, Optical Surfaces’ on-axis parabolic mirrors are designed to optimize performance for ultra-high power pulsed lasers. All surface accuracy is interferometer tested to ensure low dispersion and better than λ/10 pv waveform accuracy.
Optical Surface on-axis mirrors combined with the latest dielectric coating technology minimize pulse distortion and maximize usable bandwidth. When used with high power femtosecond lasers operating at 750-850 nm, these fast focusing mirrors can be used without degradation at power densities in excess of 100 mJ/cm2 for 50 fs pulses. Manufactured to ISO 9001-2015 certified standards, the quality and performance of Optical Surfaces Ltd. on-axis fast focusing parabolic mirrors is unmatched.
