Diffusers
Compare HYD single-sided and HSD double-sided ground-glass diffusers. The number of ground surfaces is a useful starting distinction, but the selected model must also fit the beam size and the illumination arrangement you are building.
Choosing Diffusers
- Choose the single-sided or double-sided construction required by the setup rather than assuming the two are optically equivalent.
- Check material, thickness and usable aperture against the wavelength and the holder.
- Describe the illuminated area, working distance and desired light distribution; do not assume a particular diffusion angle if it is not listed.
