Finally cost effective achromatic waveplates. Bolder Vision now offers low-cost achromatic waveplates, which can replace many single wavelength waveplates with just one component. Both quarterwave and halfwave retarders are zero-order and available for 400-700nm bandwidth. Other wavelength ranges available on OEM basis. Standard "Off The Shelf" Achromat Bolder Vision now carries an off the shelf achromat for the visible wavelength range of 400-700nm. This product costs less than 50% of other polymer achromats available in the market today! The visible achromat is a valuable lab tool, which can replace many of your single wavelength waveplates. Now, the freedom of using one waveplate for many light sources. The standard outer diameter fits into many housings sold out of catalogs today. |
