Benefits of Stock Optics in Custom Designs
Engineering projects involving optical systems have the same time and money constraints as other engineering projects. Just as electrical engineers learned long ago that integrating standard resistors, capacitors and switches could save money and reduce time-to-market, optical design engineers are learning that leveraging the investment already made in designing, producing and stocking standard optics can provide similar benefits. Standard off-the-shelf optics save money, eliminate lead
