Midwest Optical Systems

Midwest Optical Systems A leading manufacturer of custom precision optical filters, components, and imaging solutions since Unmounted filters are offered in custom shapes and sizes.

A manufacturer of custom precision optical components and imaging solutions since 1988, Midwest Optical Systems - MidOpt - is recognized as the world’s leading resource for off-the-shelf and custom machine vision filters, lenses and accessories used in industrial imaging applications. MidOpt has an extensive history in optical component design, fabrication and inspection, and continues to develop innovative new products for industrial imaging that are simply not found elsewhere. Industries served: machine vision, security, surveillance, LPR, scientific, bio-medical and NDVI. MidOpt’s complete line of filters cover the visible, near-infrared and UV spectrums. They represent the easiest, most cost effective method for insuring the reliability, stability and repeatability of industrial imaging systems. MidOpt filters are rugged; environmentally stable; heat and solvent resistant; non-hygroscopic and oleophobic, and are easy to maintain. Various designs are available for use in:

· Refining color recognition and improving separation of subject matter
· Ease viewing of desired features through contrast enhancement
· Elimination of glare or hot spots from highly reflective surfaces
· Saving cost, space and system maintenance and start-up time by eliminating the need for shrouding
· Protecting camera lenses and lighting from dust, scratching and inhospitable environments
· Enhancing lens resolving capability by greatly reducing chromatic aberrations.
· Boosting system speed and efficiency while substantially decreasing false accepts/false rejects.
· Reducing required luminous intensity, thereby saving on lighting cost and maximizing the lifespan of LED or other light sources. MidOpt offers the largest variety of threaded filter mount sizes and types in stock ranging from M13.25 to M105. MidOpt filters can be fastened to any camera lens with the appropriate mounting solution.

🔬 Optical precision matters.

Most MidOpt® filters are engineered with a superior 40/20 scratch-dig surface quality – far exceeding the industry standard of 60/40 or 80/50. The result? Cleaner images, sharper clarity, and more consistent results.

For the most demanding applications, MidOpt® also offers filters with an ultra-precise 10/5 rating – ensuring near-perfect performance in high-precision imaging.

😎 MidOpt® ND Filters: Light Control for Any Application 😎

Whether you're dealing with intense lighting or fine-tuning exposure, MidOpt® Neutral Density Filters deliver unmatched versatility across a range of applications:

💡 Light Saturation Reduction
Control extreme brightness from sources like welding arcs, bulbs or LEDs with darker ND filters – perfect for high-intensity environments.

📷 Shallow Depth of Field
Keep your subject in focus while blurring distractions. ND Filters allow wider apertures *without* overexposure.

🚁 Outdoor Aerial Imaging
Think of ND Filters as “sunglasses” for your drone – reduce brightness while maintaining color accuracy and sharpness.

⏱️ Long Exposure & Slow Shutter Imaging
Capture motion blur, reduce frame rate interference or smooth out dynamic elements like water or moving lights.

🔧 Stack & Customize with MidOpt® ND Filters 🔧

MidOpt® Neutral Density Filters feature both male and female threading, making it easy to stack filters and fine-tune your optical density (OD) on the fly.

👓 Example: Stack an ND030 (OD 0.3) with an ND120 (OD 1.2) to achieve an ND150 (OD 1.5) – it’s that simple.

Perfect for testing and adapting to changing light conditions without swapping out your entire setup.
