Crazing can occur for a multitude of reasons and it would only be complete speculation without discussion with the lab directly. On your end, the one thing you could do is determine if there is...
A great deal of labs do not like to tint and apply AR coatings because tinting UV cured spin coats often times can compromise the integrity of the hard coating to some degree. An AR stack will only...
I do not know how they are evaluating it. I just know that they have made bold claims that Bayer is outdated. I was not aware that alundum is no longer available. We use Brown Aluminum Oxide in...
It is very important to NOTE that Essilor has changed the way in which they are going to evaluate scratch resistance. They have traditionally relied upon Bayer Abrasion testing to quantify this. ...
Have you asked the lab why this is delayed? UV cured spin coatings already leave a lot to be desired with 1.67 in that they never really adhere as good as they do to other materials. Add in tinting...
It would depend on the concentration. Cleaning AR coating with isopropyl alcohol based cleaners can degrade the hydrophobic or oleophobic layer's bond to the subsequent SiO2 layer over time. Soap...
Anti-Reflection Inc. in Lithia Springs, GA is an independent AR and mirror coating lab.....almost in your back yard.
Hoya's AR coatings hold up so well because of how good their hard coating is. Anyone that has tried to create strip and dip formulations for their lenses can attest to how difficult it is to remove.
PM me and I can elaborate as well on both the Fusion and the Star.
What type of chamber are you running and whose process is this?
I am an AR/mirror coating engineer that is looking for a lab that would rent some time on a vacuum deposition system for a new coating development project. I am more than willing to work around any...
It should actually look best on CR-39. The index of refraction on most lens vendor applied HC's on Poly and CR-39 is 1.50 index....the same as most backside spin HC. There is little to know...
You should always use soap and water to remove any non-slip coating. Acetone, alcohol, or any other solvent based cleaner will ultimately damage the hydrophobic that is underneath the non-slip...
I have been trying to get the movie industry to use Natural or Clear AR's for years. It drives me crazy when I am watching a film that is specific to a time period when AR coatings had yet to be...
You don't HAVE to have a dip coating system to process a Natural AR. There is generally a slight index mismatch from lens vendor applied dip hard coatings and any spin hard coating applied to the...
What specifically are you looking for?
Manny.....were you able to solve this issue?
