Diamond Meta-Surfaces Enable New Laser Applications

Over the last 15 years, breakthroughs in the manufacture and processing of diamond grown by chemical vapor deposition (CVD) have established diamond as an excellent substrate material for high-power and high-energy optics. Diamond is a natural choice for these highly demanding applications due to a combination of desirable properties including: extremely broad transmission spectrum, low absorption, chemical inertness, mechanical strength, and the highest room temperature thermal conductivity of any material. These properties allow diamond to perform in environments and applications where other materials are simply not viable options.

Inside NASA’s White Sands Test Facility: How High-Speed Cameras Support Hypervelocity Experiments

At NASA’s White Sands Test Facility, Donald Henderson and his team spend much of their days shooting projectiles at 15,700 miles per hour. Hypervelocity testing done at the Las Cruces, NM center simulates the impact of micrometeoroids and orbital debris on spacecraft shields.

Collimated Diode Lasers

Laserglow Technologies (Toronto, Canada) has developed the Cyanea™ Series of Collimated Diode Lasers that are tuned to emit low optical noise, low duty cycle, and clean pulse shapes in the 470 nm spectral range, which coincides with the peak excitation wavelength for Channelrhodopsin-2 (ChR2).

Photon Camera

The Imaging Photon Camera from PHOTONIS (Sturbridge, MA) operates under light-starved conditions. The device features micrometer resolution, picosecond timing, a full 18-mm wide field of view, and a count rate up to 5MHz (with no added read noise). A microchannel plate detector addresses the problem of electron noise. The Imaging Photon Camera connects to any microscopy or imaging device via a standard C-Mount. In Fluorescence Lifetime Imaging Microscopy applications, the position of individual molecules, fluorescence time and diffusion, or dynamics can be determined at high resolution levels.

CMOS Scientific Camera

Photometrics® (Tucson, AZ) has announced the Prime 95B™ Scientific CMOS camera. The Prime 95B camera, built on the GSENSE400BSI-TVISB sensor, combines backside illumination (BSI) technology with large pixels and low-noise characteristics to maximize light collection. The Prime 95B, optimized for low-light microscopy, features a 95 percent QE and 11 × 11μm pixel area. The camera captures images using the full microscope field-of-view at over 41 frames per second (fps) with 16-bit images (and 82 fps with 12-bit images).

Thermocouple Simulator

The P470 thermocouple simulator is the latest in Highland Technology’s (San Francisco, CA) line of USB and Ethernet-connected Bench-top modules. It features 8 isolated channels, each capable of simulating J, K, E, T, R, S, B, and N thermocouple types, or outputting voltage in a range of ±100 millivolts with 20-bits of resolution. It can also simulate an open thermocouple. Two precision external RTD signal conditioners plus one internal RTD are provided for reference junction temperature sensing.
