Development and realization of Electro-Optics
CSTM has accumulated broad experience in design and realization of electro-optical systems including: diode laser, LED and VCSEL sources, miniature cameras, use of fibers,  glass and plastic optics.  The company has also gained vast experience in completing Electro-Optical development processes successfully. This is done by taking such measures as:  an upgradable lab setup, dynamic specification and documentation, performance analysis, simulation, robust optical and opto-mechanical design, prototyping, repeated evaluation, environmental and thermal drift control, stray light analysis, optimized component clamping, tolerance budgeting, testability, manufacturability, etc. 

Relevant projects: a custom document scanner,  a Zero CRA lens, a miniaturized periscope, a shooting simulator, a miniature camera, custom miniature glass and plastic optics, a linear angular mapping lens, Electro-Optical laser sights, and more

Analysis and budgeting of optomechanical tolerances

Characteristics of an electro-optical development
Development of an electro-optical system has several unique characteristics:
• Cost – relatively expensive
• Long development round – where the optics are usually LLIs
• Feasibility – system simulation and analysis  and  a “quick’n dirty” validation round are  essential to lower the risks
• Robust optomechanics – a good product starts with a design that is not sensitive, but allows a wide as possible  envelope  of  environmental conditions and manufacturing conditions.
• Mechanical tolerances – are often difficult to achieve practically. It is necessary to analyze and budget the system tolerances, and plan their realization.
• Inspection and sorting – testable design. Allocating resources to examine the quality of components and assemblies, and enable their grouping. 

Development of an optical system

Engineering process of an Electro-optical prototype

Development process of an Electro-optical model
CSTM aims to work in the following structured mode:
1) Specification – a well-defined TOP LEVEL specification.
2) Concept – identify optional concepts of realization. Per each concept carry a feasibility study which includes:
• A preliminary optical design
• A performance analysis of the optical system
• An analysis of the necessary implementation steps (engineering, procurement, manufacturing, testing, assembly, calibration)
• A budgetary cost estimation
• A risk assessment
3) Overall planning – of the selected concept. Such planning includes: a technical spec, a detailed engineering phase, tolerance budgeting, plus planning associated with the realization steps – i.e. suppliers for critical elements, necessary supporting equipment, aspects of evaluation and production (test, assembly and calibration)
4) Realization – according to plan (purchasing, manufacturing, integration)
5) Evaluation – compared to spec
