Introduction to ISO Preparation of drawings for optical elements and systems and a few words about other optical standards. Table 1: Structure of ISO standard. Part 1 covers the mechanical aspects of optical drawings that are specific to optics and not already covered in one of. ISO ‐2 Stress Birefringence. The cooling process can create stress within glass. This leads to polarization effects. ISO‐2 Stress.

If substitutions are allowed, I recommend using the international glass code instead of the manufacturer product label. This is presumably done with a separate document, or a note. What about gradient index materials?
If neither of these is used, the component must be manufactured from the indicated material without substitution. Find Similar Items This product falls into the following categories.
Tim Dykstra, product sales manager for Concept Systems Inc. Thus if the surface form is intended to apply prior to coating, there needs to be a note indicating this, or the coating needs to be on its own drawing. In the drawing in slide 14 et seq.

How does ISO deal with defining crystal material requirements? The best approach is to make a note on the drawing indicating that the slope is calculated on data which has been filtered with a smoothing function, such as a Chetwynd filter function. More information is provided in OP1. ISO is a metrology standard, to validate a specific damage requirement via testing.
Where do you cover the coating durability, on the drawing uso a separate document? The Zygo way of pixel to pixel gradients IS resolution sensitive when combined with noise. There is a lot of specific mention to glass. The chamfer tolerance is on the face-width, not the legs. T and R are used to specify Transmission and Reflectivity but how are the different polarizations handled, subscript?
Slope calculations in ISO for texture use this as the default. Preparation of drawings for optical elements and systems.
This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. For non-standard durability requirements, the requirement is indicated in a note. You may experience issues ido this site in Internet Explorer 9, 10 or Note that the next edition of ISOwhich is expected inwill include new drawing formats that assist with these types 1010-1 components.
ISO is the notation standard to allow you to put a laser damage requirement on the drawing.

Indications sur les dessins pour elements et syst emes optiques. Preparation of drawings for optical elements and systems Table representing data iwo optical elements and cemented assemblies BS ISO Chamfers are length of legs.
Click to learn more. Yes, any special optical material properties such as the crystallographic axis should be indicated on the drawing, but the standard does not offer any guidance on how this is done, or what happens when it is not indicated or toleranced.
What is the default for a chamfer, for example 0. The ISO series applies to optical elements and systems, and does not preclude the use on plastic optics, but neither 10110–1 it provide any assistance in specifying plastic materials properties.
Our efforts to make this the default in ISO were not successful. How about prisms, waveplates, etc. What is the length on bevel? A bevel must be specified and toleranced completely, including indication of angle, length, etc.
