Item details

Used glass Fresnel lens from cinema light. Actually made by Pyrex so it's highly heat resistant and can survive chipping.

- Convex 12" diameter, approx 1.25" height
- Lens has chips at the 3 old mounting points - typical of used lens
- 1" chip on a ring as shown in pictures
- Structurally sound - chips do not hurt strength
- May be a little dusty

Install it in a cool lighting project! A Fresnel lens will focus light into parallel rays allowing you to get a true spot light. Some are flat and some have a convex shape. FYI - Fresnel lights were used as the Transporter pads in the original Star Trek.

I have often used lenses to make light-up table tops. In this case, you should plan on installing a flat piece of glass over the lens for a more stable surface.

The last picture demonstrates using a lens as a table top and may vary from actual lens.


FAQs

3D printed objects are made by 'slicing' a digital model into many thin layers. These slices are sent to a printer that 'draws' each layer by extruding plastic through a hot nozzle.

There are a lot of different materials available now but the two most common are ABS (LEGO plastic) and PLA (biodegradable plastic) which is what Charlesworth Dynamics uses.

While the 3D prints aren't hazardous, they are not food, dishwasher or microwave safe.

They are very strong, but will break just like any plastic item if abused.

3D prints are very strong if printed properly but will break just like any plastic item if abused. Since the object is printed in layers, they will have a slightly ridged texture to them unlike a injection molded object. There is usually a 'zipper' which is a slight vertical seam that indicates where each new layer starts. They may have slight defects or blemishes and the bottom which adheres to the print bed may have some discoloration. Kit pieces may need minor clean up or trimming to fit together. This is typical of most 3D prints.

Yes, you can sand and paint 3D prints like a normal plastic model. You can even use products like Bondo Glazing and Spotting putty to minimize and smooth the 3D printed texture. Make sure to use a plastic-friendly paint.

I include a link for assembly instructions with your shipping notification, but here's a link for all assembly guides: charlesworth-dynamics.com/2013/08/instructions.html Please don't hesitate to contact me with any questions or recommendations.

On occasion I will also build items out of 'real' parts and hardware - typically I use vintage Film & TV equipment parts. I have made lamps out of old lenses and jewelry out of old camera parts. Keep in mind that these are all used parts and will show their wear and tear and age - it's part of their charm.
