ACTIVITIES
The Optical Devices & Systems division at CSIR-CSIO is carrying R&D activities involving avionics, advanced optics involving spherical, aspheric, freeform, diffractive and holographic optics, optical thin film coatings, precision mechanics, material science, system and aesthetic engineering. The developments in this area include technologies for societal, industrial as well as strategic sectors of the nation. The group provides technological solutions for import substitution in strategic sector with globally competitive specifications and also customizes its innovative technologies for end user requirements. The lab is well equipped with modern advanced optical fabrication and characterization facilities which include five axis CNC grinding machine, six axis CNC polishing machine, two axis and three axis single point diamond turning (SPDT) machines, magneto-rheological finishing (MRF) machine, conventional optical fabrication machines, range of optical characterization equipment, dual electron beam thermal chemical vapour deposition plant, LED characterization setup, Gonio spectro-radiometer, avionics and head-up display test platform recognized at national level and certified by Regional Centre for Military Airworthiness, etc.

EXPERTISE
Avionics lab works on the design and development of advanced electronics systems based on different computing platforms. The system design includes from a breadboard-level hardware design to EMI/ EMC compliant rugged PCB systems. Thermal analysis, reliability analysis, mixed signal & circuit simulation, circuit and PCB design, FPGA and DSP tools, advanced microprocessors & microcontrollers, MATLAB, LabVIEW, high level languages, etc. are few other domains in which the lab is working.
The opto-mechanical lab designs complex mechanical assemblies complying to the specified thermal & vibration MIL-standards. The optical design laboratory is involved in the design and simulation of optical components as per desired specification for different application.
The optical fabrication laboratory fabricates optical elements using conventional and contemporary fabrication processes. Among the contemporary processes, aspheric and free-form surface generations are two distinctive capabilities in the department.
The optical metrology laboratory inclusive of several modern facilities provide testing of optical and related materials in varied range of electromagnetic spectrum.
The Thin film lab is equipped with excellent infrastructure and highly trained manpower to take up challenges in the niche areas of thin film coating such as novel thin film coating for broadband antireflection, highly reflective multiband pass filters, and neutral density filters.
The holography lab is involved in designs and development of holographic optical elements for various applications such as interferometry and non-destructive testing applications.
