Smaller, Faster, Cheaper - Miniature Spectrometers, Fiber Sensors and How to Do it!
Full range optical fiber 200 – 2200nm Spectrecology has introduced a new fiber optic reflection probe using optical fiber that is good for the UV and the SWIR wavelength ranges. One fiber covers from 200 – 2200nm, a range that … Continued
Radiometric Calibrations DH-2000-CAL HL-2000-CAL Spectrometers measure an electrical signal (A/D counts) vs wavelength. Relating that signal to something meaningful requires comparison to a standard or reference. For reflection measurements, this is provided by a reflection standard (100% white or specular). … Continued
Ocean Optics Spectrometer Support from MATLAB and Instrument Control Toolbox – Hardware Support Ocean Optics Spectrometer Support from Instrument Control Toolbox Acquire data and control Ocean Optics spectrometers with MATLAB. MATLAB Support Package for use with Instrument Control Toolbox … Continued
Great new video showing spectroscopy in the field! The very first spectrometer we built in 1989 was used for oceanographic research, and we have been getting wet ever since. Now we have systems for field use, like you see in … Continued
Using Transmission “Dip” probes in gases in the deep UV – TI300 Industrial Probe Fiber Optic transmission dip probes or transflection probes utilize one optical fiber and a lens to project light across a gap to a mirror. The … Continued
Using Reflectance for Species Identification Paired STS spectrometers (upwelling and downwelling orientation) were used to identify aquatic and shoreline plants for use in controlling invasive species like the Brazilian water weed Egeria densa. The spectra of Egeria densa samples … Continued
Zero Drift and HCR Optical O2 sensors Our optical Oxygen sensors measure pO2 in gases, liquids and mixed systems such as slurries, biological samples and process streams. The fundamental mechanism is the collisional quenching of a fluorescent molecule by molecular … Continued
“Notice – August 11th 2015: For customer using the Flame-S, Flame-T, USB2000+ and USB4000+ spectrometers. We are currently aware of an issue that causes an incompatibility of these devices with Microsoft Windows 10 operating system. We recommend users of these … Continued
Reflectance of vegetation using 2 channel spectrometer system – Oceanview schematic Reflectance of sunlight from the ground is critical to understanding remote sensing, hyperspectral imagery, and is the fundamental measurement used in precision agriculture, drought detection, monitoring invasive species and a … Continued
How fast do optical O2 sensors respond? Optical O2 sensors work in gases and liquids, slurries, tissue and other fluids. In gases the response can be very fast — with T90 response rates well under 1 second. That is essential … Continued
Flame STS and SPARK (now discontinued) spectrometer sensitivity Comparison The workhorse spectrometer for Ocean Optics has from the beginning been the “S” bench. There have been various models, S1000, S2000, USB2000+, USB4000, the JAZ, and now the latest, The … Continued
A typical OceanView license allows activation on two computers at a time. If you would like to change to a different machine, you may deactivate the product key form a particular computer by going into OceanView’s main menu under Help … Continued
Ideally you installed Spectrasuite before ever plugging in your spectrometer. If not, Windows won’t find the driver, and even after Spectrasuite is loaded it still won’t find it. Here is how to fix the problem (compliments of Norm Hoffer at … Continued
We just added a new rental unit to our suite of spectrometers & oxygen sensors. The HG-1 is a handy mercury-argon atomic emission lamp that’s used to calibrate the wavelength of array based spectrometers. It comes with a battery, a 50um … Continued
Temperature stability of the new FLAME optical bench. Great news! Tests of the new FLAME spectrometer for temperature stability show a dramatic improvement over the 20 year old “S” bench design that made Ocean Optics famous. A new concept … Continued
Welcome to the Spectrecology Blog… a place for tips, tricks and longer discussion about how to make optical sensing work for you! Here is a summary of our basic Business & Design Values — Openness Our customers are innovators, … Continued
