Tailored Measurement Solutions: From Custom Builds to Adapted Standards to Fit Your Exact Needs

Are you facing challenges in your camera or sensor evaluation environment, such as standard products not meeting specifications or difficulties integrating them into automated lines?

At Tsubosaka Electric, our core strength is our integrated in-house engineering capability, covering everything from hardware design (optics, mechanics, electronics) to control software development. Our end-to-end domestic production system allows us to respond flexibly and rapidly to your needs, whether it is customizing existing products or creating fully bespoke solutions from scratch.

We go beyond simply providing equipment. By combining hardware and software into a complete system solution, we support your measurement challenges from end to end.

High-CRI evaluation light source with excellent uniformity.

High-CRI evaluation light source with excellent uniformity.

For teams building and managing high-quality products on tight timelines. KIDOBAKO, a measurement-grade area light source that guarantees luminance, color temperature, and emission uniformity.

Our surface light sources are trusted across a wide range of fields, from the inspection and adjustment of digital still cameras to shipping inspections on production lines, dynamic range evaluation, optical equipment development, and sensor sensitivity characterization. They have earned high acclaim in diverse environments, serving production floors, R&D departments, and quality control units alike.

We utilize high color rendering (High CRI) LEDs to deliver light containing energy across a broad wavelength range, from violet to red.

Standard features include Luminance Feedback, arbitrary luminance/color temperature setting, Auto-Calibration, and external communication functions. We guarantee high stability in luminance and color temperature, exceptional surface uniformity, and user-friendly operation.
Our light sources use High CRI LEDs with Ra > 95

Our light sources use High CRI LEDs with Ra > 95

Eliminating measurement variance with sunlight-quality High CRI and constant luminance correction.

We guarantee an index of 90 or higher not only for the general Ra but also for R9 through R15, including the difficult-to-reproduce red (R9). We have achieved "True High Color Rendering" that rivals sunlight, along with superior uniformity that keeps luminance and illuminance unevenness within 5%. Furthermore, our built-in Feedback function monitors and corrects luminance every second via an internal sensor. This eliminates output fluctuations caused by temperature changes immediately after startup, maintaining constant luminance at all times. This uncompromised "quality of light" and "stability" provides a highly reliable environment for camera evaluation and calibration.
Wide-ranging customization to fit real-world camera measurement needs.

Wide-ranging customization to fit real-world camera measurement needs.

Solving measurement challenges through both Hardware and Software.

While the light sources introduced here perform excellently as standard units, we also offer extensive customization to suit your specific applications, such as modifying the luminance range or creating custom PC control software. We are a system manufacturer that handles everything in-house—from hardware design to control software development and manufacturing. Our development engineers provide meticulous support for requests such as "changing the size," "linking with existing equipment," or "creating dedicated fixtures."
