That's really nice.

This is interesting, are you going to give it a try? If so please report back

I looked up lithium bromide and it's used in air conditioning systems. You can find it on the net for about £28 for 250g.

Hi John,

I have a 315m-100 so probably should be ok with a couple of meters multimode but never tried it. I will give it a go
Do you use inline beam splitters for your ratios or come out to a normal splitter? The inline's look nice for a setup.

Thank you for the advice

I have been looking at fibre optics as single mode cables are quite cheap these days. I was looking at the beam splitter cables 1x2, 1x4 etc and wondering what to use. The commercial cables all seem to be for the infrared range. Could you tell me if these are any good for splitting 532nm please or d...

Love the plate holders.
That's an idea I may borrow

I wonder why people don't use 364nm. Look at the sensitivity. Same argon ion laser. I'd be interested to see imagery shot in the UV. HOEs are easy at that wavelength, once one is accustomed to working with it. Availability really. I've been looking at 405nm upwards to about 488nm but it's the cost ...

In general there are a lot of factors, such as emulsion thickness, softness of film, dcg formula etc. However, as a general rule of thumb, at 532 (I assume the 315 emits at 532), the exposure is about 70 mJ/cm^2. The exact time of exposure depends on the light on your plate, which in turn depends o...

I just found this

I'm thinking it should do the job

Hello I have a coherent 315 100mw putting out a 100mw. I'm just in the process of setting up my "lab" and wondering which way to go, DCG or Silver. I intend to make my own plates which ever direction I choose. The question I have is, is it practical to attempt split beam transmission maste...

Hi all, The table is going to weigh around 250kgs, probably more as will be using concrete paving slabs as part of the setup. I plan to build the height with breeze blocks, put a large piece of thick mdf on top, on top of that loft foam insulation pads, the polystyrene type. Then i'm going to put on...
