Is My Light Meter Reading in mLux or Lux?

AI Thread Summary
The discussion revolves around the confusion regarding light meter readings, specifically whether they are in Lux or mLux. A user inquires about their light meter set to 2000, questioning the interpretation of a reading of 1253. Responses indicate that without additional details about the meter's make and model, it's challenging to determine the units accurately. It is suggested that if the meter is set to 2000 and the reading is 1253, it likely indicates 1.253 Lux, assuming the meter measures in Lux. Overall, more information about the device is necessary for a definitive answer.

Hi, I'm studying physics and was wondering about the light meter I used. It was set to 2000 so I could get readings, instead of 2 because the readings wouldn't show. Does this mean my values I get from the light meter is in mLux (milli) or just Lux?

I am just guessing here because I don't have the manual that came with your meter. If your setting is 2000 and the reading is 1253, then it means 1.253 Lux.

or 1253 Lux ... depends on what the units of the 2000 is

mate, you really need to tell us lots more info
Make, Model even a sharp and clear photo of the front of the unit would be extremely helpful

2000 means nothing to us if you don't tell us the unitsDave

I don't have it with me. It's measured in lux. Theres a knob that turns to 2, 20, 2000, 20000

do you have a manual for it ?

if not, there's probably one online

it would seem that it measured 1253 lux, which is a pretty bright light source.

Just an aside for light sources, the avg data projector for a home or board room is from 1500 - 3000 lux

a good number are much higher 5k to 8k lux for larger auditoriums

so, till you provide more info, no one can help youDave

Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
