Photometer thorlabs
Webphotometer (THORLABS PD130, USA). The NO gas at ppb level was obtained from a compressed gas cylinder at a concentration of 50ppm of NO (N 2 balance). The 50ppm of NO was diluted to about 420ppb by the air stream from a zero air generator. The flow rate of the gas streams was controlled at 3Lmin−1 by a mass flow controller. The WebSep 1, 2007 · The photometer consists of a light source (an LED), a light-dependent resistor (LDR) as a detector and a simple amplifier/buffer circuit to make the output suitable to drive a voltmeter. (If a high impedance multimeter is used, the amplifier could be omitted, but it does illustrate an important component of a 'real' photometer.) The LED and LDR ...

WebThere are 4 types of photometers that are commonly used, including: 1. Visible Light Reflectance Photometer. Visible Light Reflectance Photometer is a photometer that measures the reflectance of a surface as a function of wavelength. The surface is generally irradiated with white light, and the reflected light is measured after passing through ... WebMar 14, 2024 · The number of absorbed photons was taken as the average absorption in a time interval multiplied by the photon flux density multiplied by the time interval. The energy of the light beam was measured with an optical photometer (Thorlabs), which was used to determine the number of photons and thus the photoisomerization quantum yield.
Webusing a photometer (Thorlabs). The incident photon to electron conversion efficiency (% IPCE) was calculated with the equation: % IPCE = 100 ×( I1240)/(Pλ), where is the observed photocurrent in amperes per squared meter, P is the excitation light intensity in Watts per squared meter, and λ is the wavelength in nanometers.
