MidOpt® attended Automatica in Munich, Germany June 24 to 27, where there was a range of automation, robotics and machine vision technology on display. The show had everything from cutting-edge AI solutions to hands-on demos of real-world applications. It was a great opportunity to connect with industry leaders, see what’s next in smart manufacturing and come away inspired by the pace of innovation.

🌙 See Clearly at Night with A/R Coatings

Nighttime imaging presents unique challenges. One of the most common complaints? The distracting “halo” or “starburst” effect around headlights.

Anti-reflection coated lenses can make a huge difference by:
- Reducing reflections
- Minimizing glare
- Improving contrast in white (visible) light

The result: Sharper, clearer night vision and better overall image quality.

Even the best anti-reflection coatings can’t make up for poor substrate performance.

🔍 While AR coatings can boost transmission up to 99%, the glass itself matters. If the substrate only allows 88%, that’s your starting point – and thicker glass means even more loss.

When precision and brightness matter, choose filters with optimized substrate thickness to ensure your system gets the light it needs.

Efficiency begins at the core.

Every time light hits glass, about 4% is lost to reflection – per surface. That adds up fast in machine vision systems.

🔍 MidOpt® filters feature advanced AR (anti-reflection) coatings that reduce surface reflection to less than 1%.

The result?
✅ Higher transmission
🎯 Enhanced contrast
👻 Elimination of ghost images

Greater efficiency. Sharper results. Smarter design.

Visualize the Difference: Precision in Every Wavelength

In the image, you’ll see two filters superimposed over a monochromatic LED’s spectral output:
⚫ MidOpt® Bandpass Filter (red line)
⚫ Traditional Bandpass Filter (gray line)

Here’s how to see the difference:
1️⃣ Count the number of squares outside the LED curve with the traditional filter – that’s unwanted, interfering light.
2️⃣ Now do the same with the MidOpt® filter – notice the tighter fit? Less interference, greater contrast, and sharper results.

That’s the MidOpt® advantage – performance you can see.

💡 Why Filter Shape Matters

Not all filters are created equal. Some have a flat, high transmission profile that lets too much ambient light sneak in – especially at the tail ends of the LED’s output curve.

MidOpt® Bandpass Filters are different. They’re designed to emulate the bell-shaped (Gaussian) spectral output curve of the most common LEDs – matching the passband’s position, height and width for maximum performance and minimal noise.

Better alignment = better contrast, better control.

👉 Learn more: https://midopt.com/gaussian-transmission-curve/

The spectral output from a single color LED light source used in any vision application typically follows a normal Gaussian or “bell shape” profile. For a machine vision bandpass filter to be most effective, the position, height and width of the passband should approximate this bell-shaped curve...
