Our high quality in-house systems are designed to comply with BS.EN.ISO.9002. Our multiskilled and highly trained workforce work to predetermined achievable tolerances, such as:

Surface flatness <1/10 of a wavelength @ 633nm
Surface finish <10:5 scratchdig
Parallelism to <5 arc secs
Mechanical <0.02mm

Every component is individually tested and inspected for quality and accuracy to specification, cleaned and packed for next day delivery.
