Infrared wavelength

An IR illuminator provides near-infrared light, which, although invisible to the naked eye, can greatly enhance the performance of night vision devices (NVD).

Lumen meters, also known as light meters or lux meters, have a wide range of applications. Here are some common applications of lumen meters:

The sun actually sends out more light than the part we see. Just past visible violet light is ultraviolet (UV) light, and just past visible red light is infrared (IR) light. Neither is visible to the human eye. Infrared light does not depend on visible light–IR light can be detected in dark or obscure conditions. Almost everything gives off infrared light as heat. If human beings had eyes adapted to see infrared, they might be overwhelmed by all the glowing matter around them. However, animals such as snakes, vampire bats, and beetles have developed organs and receptors to detect infrared heat signatures.

You established the fact that cameras can detect IR light. Why does one camera work but not the other one? No, the rear-facing camera is not broken. It’s designed to prevent infrared light from passing through the lens; therefore, no light is seen on the screen.

IR filters (IR is the abbreviation for infrared) can effectively cut the visible rays of light and thus permit transmission of the red region of the light ...

Students may associate night vision equipment with infrared radiation. If so, be sure to point out that not all night vision devices rely on infrared radiation to “see in the dark.” Some devices amplify available ambient light, while others rely on thermal radiation.

Many of today’s smartphones have IR filters on the rear camera and little to no IR filter on the front-facing camera. It’s important to test this demonstration with both cameras before presenting it to the class. Only one camera should have the filter. This information is important for part 2. Should both cameras have an IR filter, you will need to use an older device.

Triplett offers the best lumen meters, also referred to as lux meters or lux tester, for measuring intense illumination in industrial facilities. Our lux light meters help users to verify OSHA safety requirements from various light sources in factories, schools, parking lots, warehouses, and commercial environments. Digital light meters offered by Triplett feature a silicon photodiode sensor and a spectral response filter. All our led light meters are backed with a 1-year warranty. A light meter is used to measure the light intensity of the LED, fluorescent, metal halide, and incandescent light sources in industrial and commercial facilities.

All our light measurement devices can measure light intensity from light sources up to 40k Foot Candles (400k Lux). Our lumen tester features a 4000 count LCD display. The LED light meter and digital light meter LUX/FC are provided with 2 AAA batteries and a pouch case. Our digital light meter/data logger is offered with a pouch case and 3 AA batteries. The light meter/data logger can store up to 16000 readings or can recall up to 99 readings. These light meters also feature a min/max/avg function that recalls the highest, lowest and average reading. The data hold feature helps freeze the reading on display for easy viewing and auto power off to conserve battery life.

A digital light meter is a device that measures illumination in terms of lux. A digital lux meter features a digital calculator that displays the speed and light intensity reading. Our light intensity meter meets CIE photopic spectral response.

Ensure that students understand and adhere to safe laboratory practices when performing any activity in the classroom or lab. Model proper laboratory safety practices for your students and require them to adhere to all laboratory safety rules. Do not stare at an IR light source for prolonged periods of time.

To improve photo quality and to make images appear more like what we actually see with our eyes, camera makers apply films and filters to block out infrared light. This process maximizes the amount of visible light that goes through the lens.

Though we cannot see infrared light, we can still use it. For example, a TV remote control uses infrared light to change the channels. You can use a digital camera to detect its presence. Aim a remote at a smartphone camera and press a button; you may see a light on your camera screen. The phone camera detects the light from the remote control and turns that signal into the visible light seen on the screen. When you press a button, do you see visible light at the end of the remote without using a camera? That does not indicate you have IR vision super power. That indicator light means the batteries in the remote are functioning properly.

The lux meters feature an integrated photodiode sensor, which is placed perpendicular to the source of light which assures optimal exposure. The lux meter features a digital LCD display, and readouts are shown on it. Triplett Digital meters can save measurements up to 400 readings. They possess a detection range that can be easily adjusted. The light sensor is composed of silicon or selenium material that uses a photovoltaic effect to determine the brightness of the material. These sensors generate current, which is proportional to photons received by the sensor.  The electric current is then calculated through a digital LCD in light intensity meter. The light converted into the current is transferred in the lux value on the LCD.
