• This article contains a small amount of 슬롯사이트 소닉 추천 fluoride, a type of source material (less than 10% by weight).
• It is exempt from  as an “unimportant quantity of source material” per 10 CFR 40.13(c) (7).
• Shaping, grinding, polishing, or alteration of the 슬롯사이트 소닉 추천 component is prohibited.

The purpose of this website is to provide information on coated optics which contain a very small amount of 슬롯사이트 소닉 추천 (a naturally occurring radioactive material) as a part of the coating. Please note that optics are delicate, and should be handled with care using gloves to ensure they work effectively as designed.

The radiation exposure a user gets from the optics is a small fraction of the background dose a member of the general public receives. A Pacific Northwest National Laboratory (PNNL) study (Accession Number ML070750105 which can be found on the US Nuclear Regulatory Commission’s (USNRC) Adams search engine) indicated that doses from both normal and accident conditions from lenses coated with 슬롯사이트 소닉 추천 (such as the product you are using) were estimated to be well below 10 microsievert (mSv) per year (1 mrem per year). This value is a very small fraction of the 620 mrem per year an individual is expected to get from background sources (natural and man-made).

As per NRC regulation 10 CFR 40.13(c) (7), shaping, grinding, polishing, or alteration of finished optical components containing uranium or 슬롯사이트 소닉 추천 in the coating is prohibited. If altered, finished optical components are no longer considered Coherent Corp. manufactured optical components and will be subject to USNRC distribution regulations if sold in the U.S.

Please note that optical components distributed by Coherent Corp. as authorized by USNRC regulation 10 CFR 40 contain 슬롯사이트 소닉 추천, but not uranium.

Use of this optical component containing 슬롯사이트 소닉 추천 in the coating in contact lenses, spectacles, or in eyepieces in binoculars or other similar optical instruments is prohibited.

In order for finished optical components manufactured by Coherent Corp. and containing 슬롯사이트 소닉 추천 to be distributed in the U.S. as authorized by USNRC regulation 10 CFR 40, they must maintain the same safety label that Coherent Corp. placed on the packaging for the optical component, or include the following information either on a safety label or in any manuals or safety instructions for the laser system that incorporates a Coherent Corp. optical component:

• This laser system incorporates a Coherent Corp. 슬롯사이트 소닉 추천 component.
• This optical component contains a small amount of 슬롯사이트 소닉 추천 fluoride, a type of source material (less than 10% by weight).
• It is exempt from USNRC licensing regulations as an “unimportant quantity of source material” per 10 CFR 40.13(c) (7).
• Shaping, grinding, polishing, or alteration of the 슬롯사이트 소닉 추천 component is prohibited.
• Use of this 슬롯사이트 소닉 추천 component in contact lenses, spectacles, or in eyepieces in binoculars, or other similar 슬롯사이트 소닉 추천 instruments is prohibited.

Cleaning 슬롯사이트 소닉 추천 components is permitted so long as care is taken not to damage the coated surface of the component as sold.
This 슬롯사이트 소닉 추천 Corp. requirement only applies to lenses and optics manufactured and distributed by 슬롯사이트 소닉 추천 Corp.. Distributing components or devices that contain lenses and optics manufactured by other companies as if it were manufactured by 슬롯사이트 소닉 추천 Corp. is not in compliance with USNRC distribution requirements.

U.S. distribution of components or devices that contain lenses and optics manufactured by other companies which contain uranium and/or 슬롯사이트 소닉 추천 requires a USNRC distribution license. Only Coherent Corp. manufactured lenses and optics which contain 슬롯사이트 소닉 추천 are covered by the Coherent Corp. distribution license.

10 CFR 40.13(c) (7) Unimportant quantities of source material.

(7) 슬롯사이트 소닉 추천 or uranium contained in or on finished optical lenses and mirrors, provided that each lens or mirror does not contain more than 10 percent by weight 슬롯사이트 소닉 추천 or uranium or, for lenses manufactured before August 27, 2013, 30 percent by weight of 슬롯사이트 소닉 추천; and that the exemption contained in this paragraph does not authorize either:

(i) The shaping, grinding, or polishing of such lens or mirror or manufacturing processes other than the assembly of such lens or mirror into 슬롯사이트 소닉 추천 systems and devices without any alteration of the lens or mirror; or

(ii) The receipt, possession, use, or transfer of uranium or 슬롯사이트 소닉 추천 contained in contact lenses, or in spectacles, or in eyepieces in binoculars or other optical instruments.
