Making A DIY Anamorphic Lens

If anyone has ever considered making their own lens, but felt it would be beyond their capabilities, this DIY article that was published sometime ago might just change your mind..

It's a very straight forward description of what's required to produce a very reasonable Anamorphic lens..
Anyone with any Carpentry skills should be able to make up the lens box..and the method of setting up the prisms is clearly explained and shown..

Re: Making A DIY Anamorphic Lens

I'd make one of those in a heartbeat, but the picture would be wider than the room. Sure would be nice to get extra screen size with no major degradation in picture quality.

Re: Making A DIY Anamorphic Lens

How wide is your room!!?
My theatre room is only 10'6" wide, but I have an 8' wide scope screen..

One of the advantages of scope screens is their low profile, which means you have more space to mount speakers above or below the screen, in narrow room situations..

Re: Making A DIY Anamorphic Lens

Excellent article, Prof. I wonder if the bigger the prisms are the less pincushion effect there will be.

Re: Making A DIY Anamorphic Lens

Mike...Unfortunately no..
The only thing that affects pincushion is the throw ratio..The longer the throw ratio, the less pincushion effect..

The advantages of the larger prisms is that they can be used with a variety of projectors, and possibly help to collect maximum light output from the projector..

Re: Making A DIY Anamorphic Lens

Whilst the DIY lens has tradionally being a prisms lens, it may be possible to do (more difficult and expensive, none the less) to make a DIY cylindrical.

Anyone interested in discussing this?

Re: Making A DIY Anamorphic Lens

You have my attention. Are there any advantages to a cylindrical lens over a prism lens?

Definetly interested! This is intriguing. I like cheap DIY as long as it works.

Many, including the ability to focus, which you can not do with prisms...

Re: Making A DIY Anamorphic Lens

Sounds very interesting Mark...
Are these cylindrical lens elements readily available?
