Welcome To Chromar

We have more than 30 years experience in development of optical systems for defence,  aerospace and some industrial applications.  We define optical system specifications and analysis, do optical and opto-mechanical detail design, development, manufacture, assembly and testing of these systems.

Our products and services includes a range of rugged a-thermalised refractive lenses for C-mount or CS-mount CCD’s, Multi-spectral catadioptric lenses for Vis/NIR, NIR/MIR and MIR/FIR as well as special projects on ad-hoc basis.

Projects and Experience

  • Optics for Sumbandila Satellite (Main Camera, star camera and horizon sensors)
  • Optics for world-leading Helmet Tracking System for military aircraft
  • Seeker optics for range of missiles from reticule pulse modulation to imaging IR
  • Multi-spectral refraction system for IR scene simulation
  • Various optics for tank sights and aerial surveillance
  • Laser scanning systems and goniometers
  • Range of optical test equipment and much more

Applications:

  • scanning systems
  • test equipment
  • reticule missile seekers
  • imaging IR systems
  • surveillance optics
  • tank sight optics
  • telescopes
  • goniometers
  • satellite optics
  • LED cap lamp technology
  • Infantry optics

These products are suitable to be used in commercial, industrial, security and military applications.

Chromar Technology has also developed optics for space applications such as the image shown above, which is a cross-sectional view of the Sumbandila satellite main camera lens: 400mm EFL, F/# 5, attaining diffraction limited performance over the entire image of 52mm and extended spectral region of 420nm –  950nm.

This lens was also athermalised for its operational temperature range to eliminate the need for real-time refocussing. The satellite was developed by Sunspace & Information Systems  in Stellenbosch, South Africa. Click Here to see an image of Cape Town, and click on the image below for a full resolution image of Sossusvlei in Namibia. These images were taken by the satellite from an orbit altitude of 505km. Note that the images have been cropped to only about 1/3 of the widths recorded, i.e. only 16 km of the actual >48km wide scan. These pictures and others can be viewed in full resolution on the Sumbandila mission blog-spot http://sumbandilamission.blogspot.com/.

Order / Pricing

As these lenses are not for the general consumer market, manufacture of components are only commenced on order (requiring a 35% deposit), after which assembly, testing, packaging and shipping is done. Therefore a lead-time of 14 to 18 weeks is required. Fixed prices have not been established yet, presently in process. Quotes can be prepared on enquiry. Unit prices are drastically influenced by quantities.

Special projects can be negotiated.
