CONTRACT MANUFACTURING

PRODUCT DESIGN AND REVERSE ENGINEERING

At Lensel, we have diverse manufacturing capabilities including glass optics, plastic optics, coatings and assembly at our single integrated facility in Pune. We also have an engineering team containing optical and mechanical engineers. Finally, we are located in one of the most concentrated industrial zones in India (just 1 km from the Tata Motors car and truck manufacturing plant), which gives us access to a wide range of engineering service providers in our vicinity.

We have used this mix of our capabilities and skills and those of our engineering associates to help our customers with every step of the product realization process from design to prototyping to bulk manufacture. We are very careful about the Intellectual Property Rights of our customers and always sign strict Non-Disclosure Agreements with them, which we follow in letter and spirit.

SOME OF THE PRODUCTS RECENTLY DEVELOPED AT LENSEL BY OUR CUSTOMERS

GALILEAN TELESCOPES WITH LED LIGHT.

The entire optics used in this system consisting of a BBAR coated plastic doublet (PMMA and PC lens), BBAR coated plastic bicave, LED optics and assembly was developed at Lensel.

The molds for the various mechanical parts used including the components of the hinge, the LED light, the LED light attachment and the Ocular casing were also developed by us.

We also implemented the electrical design of our customer which included a customized Battery Case with intensity settings and LED driver circuits.

Thus we helped our customer with the optical, mechanical and electrical development of his product and continue to supply it exclusively to him.

GLASS LENS ASSEMBLIES

We have designed, prototyped and supplied various customized glass lens assemblies including all types of imaging systems, telephoto lenses, telecentric lenses, fiber optic couplers etc.

We assist our customers in every step including specifying the optical requirements, lens design, mechanical design of housing, prototyping,pilot runs and finally bulk supply.

Our optical designs are done by our Chief Optical Engineer, Mr. S. S. Rege who is also one of our directors. Mr. Rege has a BS and MS in Optical engineering from the University of Arizona, Tucson, USA. He has worked as an optical research engineer in the US prior to joining Lensel and has 5 US patents in optical design.

OTOSCOPE

We have developed complete imaging systems consisting of aspheric plastic lenses for use in the medical field. A US based medical devices company recently developed an Otoscope with us using 3 aspheric lenses. Due to the biological limitations of the human ear, the front lenses of this system were only 2.20 mm in diameter with complex, multi-coefficient higher order aspheric surfaces. The product produced sharp images of the inner ear and has been approved by our customer. We manufacture the lenses, coat them, assemble them and do the complete product testing for the customer.

PERISCOPE FOR NUCLEAR REACTOR

We were approached by the scientists at the Bhabha Atomic Research Center (BARC) in India to develop and test the optics for a Periscope to be used to inspect the dome of a Nuclear Power Plant in India.

We helped with the design and tolerancing of the lens layout. We also manufactured all the lenses, prisms and other optical elements needed for the Periscope Layout, including lenses using cerium stabilized radiation resistant glass.

Finally we created a 30 foot long optical rail and fabricated stages and mounts for all the optical components. The entire Periscope optics was mounted and aligned on this open rail to verify the optics of the Periscope before it was shipped to the site.

REVERSE ENGINEERING OF OPTICAL LAYOUTS

Our skilled team of optical engineers is able to reverse engineer any optical system. Our thorough study includes de-bonding of doublets, study of all optical parameters, determination of optical glass used and transmission curve of the coating used. Using these techniques that have been honed over the years, we have achieved a very high success rate in our reverse engineering jobs. Some of our more challenging reverse engineered complex multi-lens systems include a Night Vision Binocular for an Indian defense company, a range of medical imaging devices for a Brazilian customer, fiber optic coupler etc
