The MidOpt LP330-25.5 protective window is the lowest-cost alternative for dust covers or protection of optical components. No anti-reflection coatings are provided; parallelism and surface quality are excellent. A slight reduction in infrared and deep red transmission may also be associated with the LP330. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
