Philtec recently performed calibration tests on their sensors, using different target materials supplied by their customers. Calibrations were made to 4 different metal targets without adjusting the gain output control. Only the SNR control was varied to 3-4 volts max to optimize the signal for each target. The four targets were: Dull Metal: A dull … Continue reading
The rapid expansion of the World Wide Web and increased connectivity requirements have generated an explosion in optical communication systems. In optical fiber-based communications, optical signals are transported on a light wave. Each wavelength (or frequency) of light transmits a separate data channel. Over long distances, Erbium-Doped Fiber Amplifiers (EDFAs) amplify these signals to ensure … Continue reading
Here is another amazing astrophotography image shared by Terry Hancock and Tom Masterson. The photo above was taken at Purdy Mesa, CO. Terry says about this image: “In this image taken on the early morning of Dec. 3, 2021, at Grand Mesa Observatory, Comet C/2021 A1 (Leonard) is seen moving past Globular Cluster M3 in … Continue reading
To appreciate the precision of a snowflake it is not necessary to stand out in the cold! This year snowflakes come trapped in glass and are visible only with the help of polarized light. Single-pass welding of 1-mm thick, fused silica glass is enabled using the BiBurst function of the CARBIDE femtosecond laser from Light … Continue reading
Philtec produces threaded tips in a variety of lengths and sizes. Some are easy to machine, while others are very difficult. Any diameter thread with a long length is more difficult. Read Philtec Application Note No. 73 to see Philtec’s Table of Standard Minimum Thread Sizes for Sensor Tips. This table shows standard threads with standard lengths … Continue reading
