Optical Performance
MidOpt filters are specifically made for industrial imaging applications and designed to offer high transmission, block unwanted light and improve overall image quality. MidOpt filters offer an anti-reflection coating that enhances peak transmission performance by more than 90 percent. In addition, most MidOpt Bandpass filter designs are created from precision-ground, double-side polished glass to produce exceptional parallelism and fractional wave-front error.

StablEDGE® Technology
MidOpt’s StablEDGE® filters exhibit reduced angular dependency. Traditional bandpass filter designs are highly sensitive to the angle at which light strikes the filter and are far from optimal at wider or shallower angles of incidence. In contrast, peak transmission of MidOpt StablEDGE® filters is not significantly altered, and effects due to short shifting are minimized. This is important because of the ever-increasing demand to fit inspection applications into tighter spaces. The need to use shorter focal length (wide angle) lenses will continue to increase, and imaging at wider angles will continue to become a greater problem.

Unmatched Durability
MidOpt filters are designed for durability and high performance in even the harshest environments. Unlike conventional filters which may delaminate or deteriorate in undesirable settings, MidOpt filters are hard, dense and environmentally stable. They can withstand repeated cleaning, solvents, high heat, humidity and vibration without degradation. The unmatched stability of MidOpt filters ensures long-term reliability and accuracy. MidOpt stands behind the quality and performance of every filter.

Exceptional Quality
All MidOpt filters are closely inspected for exceptional surface quality and meet or exceed a 40/20 scratch-dig criteria. To ensure every filter upholds the highest standards, state-of-the-art Spectrophotometer technology is used to test filter performance. Each filter must pass strict guidelines for proper transmission, full-width half-max and out-of-band blocking.

Product Availability
MidOpt offers same-day shipping and is home to over 2,000 in-stock mounted filters, ranging in size from M13.25 to M105. A variety of mounting solutions are also available, including options for applications without filter threads, custom mounting solutions and MidOpt’s exclusive 25.4® C-Mount filter that threads into all C and CS cameras.
