Optical Coatings

We offer 96%, multi-layer (4)

enhanced aluminum coatings. Standard Aluminum coatings are available upon request. Both of our cryogenic systems now utilize Ion sources to produce our best and hardest coatings.

In side-by-side comparisons, our coatings are brighter and more brilliant than the competition.

We remove old coatings and center spot at no additional charge, providing you send us the center spot.

For those of you in Southern California, we welcome "walk-ins" Monday-Friday, but ask that you make an appointment.

Ostahowski Optics, Inc. uses a dilute solution of hydrochloric acid and copper sulfate to remove old coating (green river). This solution safely removes the old coating without affecting the underlying glass or optical figure. This method has been used safely for years; it is gentle and effective.

*Ostahowski Optics, Inc. is not liable or responsible for prior surface damage due to previous improper cleaning and/or coating techniques. Often times, this damage cannot be seen until the original coating is removed!

We assume no liability for damage of any kind. We will use utmost care in handling your optics for coating, but our coatings will not fix scratches, sleeks, a lack of a complete polish or figuring defects.

Optic recoats: It is very important to let us know in advance if you suspect your optics have a di-electric coating or a base coating of Chrome, Inconel or Nickel. We cannot remove di-electric coatings.

We can remove the base layer if it is Nickel, Inconel or chrome. We do not see this very often and it can add to a slight delay in processing your order as well. A modest increase in cost may apply.

Our optical coatings are guaranteed for one year. We cannot warranty against coating damage caused by moisture, acid dew, acid rain, chemical exposure, neglect, animal or insect excrement, improper cleaning methods, or improper storage. The use of aerosol propelled canned air voids the warranty due to the chemicals in them. The propellant may spray onto the coated surface...yuk!

Our coatings are completely strippable.

Optics that are larger than 28" may require a slightly longer lead time to complete.
