Daystar Blocker & Trimmer Restoration Quantum PE/University

Darkening or degradation of the image: 
Daystar solar filters older than 10 years do frequently require service. The most common service requirement is the replacement of 2 optical components which age and darken over time. Those are the 'blocker and trimmer' elements. As these two elements age, they darken and lose contrast concentrically from the outside to the inside. A user will notice the view slowly developing poor contrast towards the outside of the aperture. On a visual inspection of the filter, the red side of the filter will show a dark or mottled, doughnut shaped ring forming from the outside in. The gold side often evidences as speckles or dots in the same ring pattern from the outside in.

Please DO NOT open your filter yourself and attempt to perform any repairs on your own. There are no user-serviceable parts inside; and simply twisting the optical elements in your filter stack can cause irreparable damage to the system.

• Repair service for these two elements is $1995.00
Replaced blocker & trimmers are warranted for another 10 years when in a Quantum or T-Scanner housing.

This is normal age-related element failure which occurs slowly sometime after 10 years. Climate conditions in which the filter is kept will either accelerate or decelerate the speed in which this darkening occurs. A warm and moist environment will speed this deterioration process. Users should try to store the filter in a dry, room temperature environment. Some users in tropical zones use desiccant packets in their storage to protect the filter. There is no precise forecast to how long a filter will function. We have found filters kept in constant operation to still be functioning perfectly after 25 years, while others fail in 12.
