LightHawk® -
Teledyne Monitor Labs
TML's LightHawk® Opacity/Dust Monitor offers advanced technology for outstanding performance and reliability as an opacity, optical density or dust concentration monitor. The LightHawk® utilizes a patented solid-state light emitted diode that is electro-dynamically pulsed by an oscillator at a frequency of 2500Hz. Unlike slowly chopped incandescent and laser light systems, this pulsed light source enables guaranteed rejection of sunlight as well as artificial light sources. The LED has a proven life in excess of ten years and is warranted by TML for eight years. This extended life ensures TML LED based opacity monitor is the least expensive system to operate in the world. With our op-amp and special electro-optical bench design, the LED light source is extremely uniform with Ultralow drift and requires no other light source for stabilization. Ideal for all opacity applications.

Lisle Corp.
If the bulb lights up, continuity exists. If the bulb fails to light, the circuit is open. Not for use on live circuits, but incidental contact with 12V supply will not burn out LED bulb.

MRC ltd.
A fluorometer measures the light or radiation emitted by fluorescent objects. Fluorescence occurs when light of a specific wavelength strikes and electrons in the sample.MRC provides a wide range of Fluorometers for Laboratories.

PPTACT1CS -
Power Probe Group, Inc.
THE PROBE 12-Volt Test Light with Haptic Feedback, (PPTACT1CS) this tool vibrates and lights when voltage over 12 volts is detected. When a voltage is below 12 volts, this functions as a standard test light. Just push the button and go! Shows positive voltage, ground, and continuity “all in one tool” with haptic advantage.

Line Follower -
SparkFun Electronics
The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.

mks Ophir
Ophir has several ways to measure intense pulsed light IPL radiation used in cosmetic treatments. The light from these sources is broadband and usually has a high divergence. Furthermore, the light source is often coupled to the skin via an index matching gel. For these reasons, we need special solutions to accurately measure the energy of the IPL pulses.

Feasa Enterprises
Couplers can be used to split light from one or more fibers onto two or three fibers or to combine light from two or three fibers onto one or more fibers.
-
TF16-N -
optek
The TF16-N is a high precision turbidity meter for installation into pipelines measuring scattered and unscattered light at two independent angles in various liquid process streams. The ratio of scattered to un-scattered light can then be correlated.

Buehler
Microscopes offered by Buehler generally fall into the categories of stereo microscopes, upright microscopes, or inverted microscopes. Inverted microscopes are commonly referred to as metallurgical microscopes. Microscopes may offer episcopic (reflected light) observation, diascopic (transmitted light) observation, or both possibilities. Illumination may be delivered in bright field mode (BF) or dark field mode (DF), and several techniques such as differential interference contrast (DIC) and polarized light microscopy make use of the nature of light to reveal specific pieces of information when studying materials.

Parallax Inc.
The ColorPAL is a miniature color and light sensor which, through its RGB LED, doubles as a color generator. For sensing color, the ColorPAL uses its LED to illuminate a sample, one color component at a time, along with a broad-spectrum light-to-voltage converter to measure the light reflected back. The amount of light reflected from the sample under illumination from each red, green, and blue LED can be used to determine the sample’s color. The ColorPAL works with non-fluorescent reflective surfaces, preferably those in contact with its light shroud.
