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 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 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
