I spoke with the manufacturer about custom large dual focus fresnels. These will be custom manufactured for us. The specs are:

Dual focus fresnel; useable W= 330mm H= 240mm,
Forward focal length= 340mm, rear FL= 220mm

The cost per DF lens will be $49.95. The turnaround will be 30 days on the initial order.

Who's interested?

I would have been, but i just ordered a regular 12.2" lens through your group buy

Going to take awhile on the big fresnels. It's a large minimum order. The 310s are available and do the job nicely. I'm using a 310 now. I'm trying to use my business to get us better lenses. I'm asking if there's any interest in this lens.

It's just a shame 2cm costs so much more, it's all about demand but... Seems so silly

What is the grooves per inch.

.5mm BUT this is a custom order so if you guys have a request on a higher groove count let me know.

Dnt32 · 5th February 2004, 09:37 PM

What Lcd sizes will cover just up to 15 in. or will it cover a 17 in.

Am I wrong? I though the smaller the groove the Guess I misunderstood.

Brainchild,
Just seeing if you have heard anything about the shipment. How much longer are you expecting it to take to get the lenses sent out? I am not rushing you, just trying to do a little schedule planning. Take care.

Hoping the lenses will be at the terminal tomorrow or Wednesday. As soon as they arrive we start shipping. I'll also be placing another order immediately following this receipt.
