What Is the Image Sensor Chief Ray Angle Spec?

Endoscopes offer a minimally invasive or non-invasive method of observing areas of the human body that would typically be inaccessible without invasive surgery. The high-resolution images from the endoscope provide an exceptional visual interpretation of internal anatomy accessible from orifices naturally present in the human body or through incisions. Medical and industrial applications in optics, […]

Resolution and MTF Testing

In the past, when sensors only offered at most 640 pixels, it was easy to make an imaging lens that could outperform the camera’s sensor. Today, with pixel sizes less than 1 micron,  pixel count on sensors have significantly increased —sensors now regularly have over six million pixels. To keep up with this technological advancement […]

Eric Storm

Meet Eric Storm, Principle Assembly Technician

Eric Storm, our Principle Assembly Technician, has been with us since early 2019. He’s personally worked through most of our customer’s challenges to solve fixturing and alignment problems with those tricky < 2mm optical assemblies required in robotic surgical units.  How Eric Became a Gray Optics Team Member Dan Gray and Ted McHenry were lucky […]

What Does an Optical Engineer Do?

In physics, optics is the study of light, a broad field of research and engineering that includes aspects like rays, waves, and photons. Although the term “optics” is often associated with sight, optical engineers focus more on the behavior, properties, and creation of light. Here we’ll go into more detail about what optical engineers do […]

What Are Endoscopic Cameras?

One of the most applied imaging methods in medicine is endoscopy, and endoscopic cameras are one of the most technical demanding devices. These systems allow medical practitioners to examine and inspect the interior of bodily organs, joints, or cavities for diagnosis and treatment purposes. At Gray Optics, we specialize in solving complex optical, mechanical, and […]
