Want coloured plastic sheets? You can find a whole host of coloured acrylic sheets that are sure to bring a pop of colour to any project. For an alternative to coloured PMMA sheets, look no further than our coloured acrylic sheets. Often called Plexiglas, Acrycast or Policril, our coloured acrylic sheets are highly durable, with high light transmittance that is used in many household and commercial applications. All of our coloured acrylic sheets are UV stabilised ensuring t..

Acrylic tubes are optically pure. Our transparent PMMA tubes are often used in the stand- and exhibition building, in the furniture/interior design branches and mostly for technical applications such as reactors.

PLEXIGLAS tubes can be cut, sanded, drilled, etc. with the appropriate tools. They require high cutting speeds and effective cooling as their low heat conduction can easily lead to overheating and local thermal stress.

PMMA / Plexiglass sheets - 30% clear Plexiglass sheets, compared to other materials for example to polycarbonate are not as robust to shock loads and have a significantly lower thermal resistance, but the Plexiglas / PMMA (plates) are cheaper compared to solid polycarbonate. In comparison with silicate glass, Plexiglass sheets are 2.5 times lighter and have 5 times higher impact resistance. PMMA sheets have ability to transmit light and UV radiation above, it is superior i..

PMMA tubes are reasonable UV stable and weatherproof but are not designed for long-term outdoor applications. They will yellow if they are outside for a long period.

Focallength estimation

For computing the baseline distance of a stereo camera you further have to enter the minimum depth at which you want to be able to perform stereo matching and the considered disparity range. The baseline distance is then computed such that depth measurements at the minimum depth will have the maximum disparity value.

Excess friction, especially with Acrylic tubes can cause melting which leads to a tacky surface and difficulty machining. Drilling should never be performed without using some water-based cooling lubricant (i.e. an emulsion). For eliminating internal stress annealing may be necessary.

This calculator helps you selecting the right lenses for your cameras. It does so by computing the desired focal length, the corresponding field of view and the expected depth of field. In case of a stereo camera, such as our Karmin3 3D stereo camera, the calculator also helps you selecting the baseline distance and it provides information on the expected depth error.

High-quality, design-orientated applications within the architectural lighting industry can be easily created with our Acrylic tubes. You can create impressive lighting effects using our Satin Frost PMMA Tubes which are an innovative solution that fits particularly well for Lighting and architectural applications. White or frosted satin surface finishes provide excellent diffused light creating a velvety nonglare surface.

You have several options for determining the focal length: you can enter the focal length manually, specify the desired field of view, or determine the focal length from the object of interest’s size and distance.
