All final assembly and test is carried out in a controlled environment cleanroom containing Class 100 laminar flow air booths.

The department is divided into four flexible flow line manufacturing cells, under the control of team leaders who are responsible for the complete assembly and test process though to final despatch.

The Test Engineering Department provides and maintains Test Equipment to support the Quality Control of products in development and Production. Test Equipment is designed primarily for in house use although the company have produced Test Equipment and procedures for acceptance testing of our products at customer premises. Much of our Test Equipment is purpose built specific for the particular product requirement.

The department use interferometers, some commercial and some designed in house, over a range of wavelengths from 632 nm right up to 10.6µm, to test our products and components for optical quality and alignment. We also have an environmental facility with 5 thermal chambers and 2 vibration machines on which we carry out Environmental Stress Screening and Qualification Tests.

The staff of approximately 70 highly trained and multi-skilled technicians provide a flexible capability to produce a wide range of products varying in both complexity and quantity

Production rates vary from 1-off prototypes up to volume of 500-off per month.
This product mix is extremely variable, with up to 30 different products being assembled at any one time.
