The dispersion of white light occurs when light travels through a prism. The splitting of white light into its seven distinct colours is called dispersion.

202495 — How to read a light meter? A light meter is a tool to meter your light. Some photographers think it is something from the old days.

2024410 — Hey,. I have multiple of these saved images with lines on them, i would like to select all of them and remeasure them with a new scale

These devices help photographers to measure several things, giving them accurate information about shutter speeds and other data. Sekonic meters come with a ...

This is a pretty neat way to glow up. Light in the fiber optic cable zooms through the core by constantly bouncing off of the edge of the molded plastic, a principle called "total internal reflection" (which also kinda sounds like a very expensive meditation island retreat). When the light pipe doesn't have total reflection, you can get a nifty lighting effect from the light illuminating the plastic tubing.

We present the latest solutions, which are modern LED light lines with a uniform lighting effect along the entire length.

A laser beam is collimated, meaning it consists of waves traveling parallel to each other in a single direction with very little divergence.

Consistent light levels are essential to guarantee repeatable results in Machine Vision systems. Typical systems that monitor, regulate, check, analyse, sort or classify products need high precision and repeatability, and in many industries, only 1 in 100,000 reject products can be tolerated. To meet such high tolerances, the reliability of the system measurements needs to be even better. For example, if you are making a simple caliper measurement then a 10% reduction in light level can typically cause a change in the measured values of around 0.5% which can severely affect the reliability. For this reason, light intensity must be closely regulated.

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with ...

Gardasoft controllers drive lighting with a constant current drive which will give stable and repeatable light output. For simple applications involving a single light, the entry level RC120 will provide stable and repeatable illumination for machine vision systems. This controller has an Ethernet interface and can be easily configured using its internal webpages.

A number of factors will affect the intensity of LED lighting. These include the age and temperature of the light and external factors such as ambient light or dirt on the light. Although some machine vision lights have a voltage rating, their light output is actually controlled by the current through the LED and not the voltage across it. In fact, a very small voltage change will cause a much larger change in brightness. For example, a 1% decrease in voltage can cause a 10% reduction in light output. For this reason, a lighting system that is driven by a voltage source will be inherently susceptible to any electrical interference or variation in power supply.

Illumination is the most critical component of machine vision systems because a poor-quality image makes it more difficult to get reliable data. Gaining precise control of your lighting can be crucial, particularly since factors such as the direction, wavelength and intensity of the illumination can all affect the captured image.

Many studies have looked at using infrared saunas in the treatment of long-lasting health problems and found some proof that saunas may help.

All you need is a way to get a ton of photons into your light pipe, and that's what this is! It's Fiber Optic Light Source in a cute blue color. It's a high powered LED cluster, you need to power it with 9-12V and 100mA of current, the metal body acts as a heat sink. Then, installation is a breeze. Just loosen the clear knob on the LED emitter and slide one of our fiber optic tubes.
