MIRROR STARTER KITS

The following are starter kits consisting of items listed elsewhere in this catalog. All the mirror blanks and grinding tools have a plano surface (flat surface) unless otherwise noted. The grinding and polishing compounds are listed and are believed to be adequate to complete a finished mirror, however, the actual quantity required will depend on the fabricator's skill.

PLATE GLASS VS. PYREX GLASS BLANKS

If a decision has to be made between a kit containing a Pyrex blank and one containing Plate glass blank, it should be noted that plate glass blanks are used by many of the commercial telescope manufacturers in their product lines costing in the hundreds of dollars and their scopes have received high ratings in reviews that appear in national astronomy magazines.

The major difference between a Pyrex blank and a plate glass blank is the expansion coefficient of material when they are exposed to temperature variations. Pyrex is more stable in this situation while plate glass requires more time to adjust to the temperature changes. However, once the plate glass has normalized (adjusted to the surrounding temperature), the image produced would be the same for either mirror blank type assuming both have an equivalent polished surface figure.

The only other time Pyrex blanks may be preferred is if the person polishing the mirror is attempting to approach perfection/a precision surface which requires a stable blank to reduce the amount of hand work that has to be done to correct the curve. Usually, these individuals have had experience before and have access to testing equipment to check their progress as they work on their blank.

For most amateur telescope makers it becomes an issue of personal preference as to which of the two materials to use as a mirror substrate. For the initial attempt and for general observation, either material should be adequate to make a functional mirror.
