What do you do if your lens coatings have become damaged?

In case your lens coating is damaged, the right way is to consult an eye specialist. In some cases, damaged coatings may be repaired or replaced by the manufacturer or a specialized optical laboratory. In situations where the damage is extensive or affects the overall performance of the lenses, it may be necessary to replace the lenses altogether. It is important not to attempt to repair the coatings yourself, as this can cause further damage to the lenses.

I have used a simple way of cleaning not just my camera lens abut also my specticals (eye glasses). I use a soft piece of toilet paper to first clean the lens using clear hand wash liquid. The carefully use another piece of wet toilet paper to dry the glasses. I do that with my camera lens as well and have being doing so since over 10 years and have had good results

Lasers can sometimes burn the plastic components of lens holders, causing the release of smoke and debris. This material can settle on the lens surfaces, particularly at the edges. These deposits can sometimes be cleaned off.

Always conduct your own assessment to determine the extent of the damage and this will inform your next steps. By doing this you will be able to note what is the cause and be able to implement preventative measures going forward.

Que tipo de da?o presenta el revestimiento de las lentes? Esa sería la primera pregunta y acción a realizar. Después de identificada la naturaleza y localizado el problema, utilizando cualquiera de los medios disponibles, microscopía óptica o electrónica, fuentes de luz externas etc, podremos decidir en base a esto, la acción a tomar sobre los lentes, una posible reparación del recubrimiento o sustitución completa por iguales o similares.

The first procedure should always be to blow with compressed air to clean off loose particles. While using a compressed air can, always keep the can upright and keeping the lens tilted at an slight downwards angle, start blowing air from top to bottom. Only if there are oil, finger prints or sticky dirts, then the surface should be cleaned with a lint free wipe first and last option is to clean with IPA, making sure the IPA is pure and doesn't leave any residue. One dry lint free wipe clean can be done after an IPA clean, to remove IPA residue. Last option can be to use a ultrasound sonicator only if it is a single lens and not an assembly.

When dealing with small lenses, cleaning their surface can be really difficult. From my previous experience, I have found that using an optically graded Q-tip, lightly moistened with isopropyl alcohol, can be effective for this task. It's crucial, however, to ensure that the alcohol does not come into contact with any glued components, such as metal rings around the lens or joints within multi-element lenses. Alcohol can weaken these adhesives, potentially leading to further damage or misalignment of the optical elements. Hence, precise application and control of the cleaning agent are essential to maintain the integrity and functionality of the lens.

El segundo paso y que es siempre recomendable hacerlo con regularidad sería limpiar nuestras lentes. En mi criterio, lo mejor sería comenzar por utilizar el aire comprimido para eliminar cualquier partícula de grano grueso que pueda rayar la lente. Continuar luego con un pa?o suave que no deshilache y algún líquido no abrasivo como alcohol isopropílico. Evitando hacer demasiada fuerza. Esto eliminaría el polvo, la grasa de nuestros dedos etc.

En mi experiencia, reparar los da?os en las lentes es un proceso sumamente cuidadoso pues podemos da?arlas más. Generalmente cuando los da?os son menores, podemos solucionarlos de forma temporal, con un nuevo recubrimiento o con una buena limpieza que disminuya parcialmente los efectos de estos da?os. Pero siempre es aconsejable para futuros trabajos, reemplazar las da?adas.

I've heard that once a lens has become damaged it's best practice to replace the lens rather then wasting money and time as the process to fix the lens can be more than the original cost of the lens itself. Thus saving time down which is typically of essence.

In my experience, it is often best to replace a damaged lens. Despite possible cleaning and minor repairs, fully restoring the lens to its original performance can be exceedingly difficult. Damage such as deep scratches, significant delamination, or severe discoloration usually compromises the lens's optical properties irreversibly. Replacement not only ensures optimal functionality but also avoids the risk of recurrent issues or degraded performance that might arise from attempting to salvage a significantly compromised lens.

A damaged or dirty optical coating can have significant consequences on system performance level. For high power laser systems you can clean as much as you want but you will only make it worse. Best advice is to avoid damage and/or dirt from happening but unfortunately shit happens. Therefore, plan ahead and implement contingency into your optical and mechanical design : A simple but very effective approach is to design the optical system (optics including mechanics) such that the beam propagates through the lens slightly off-axis. If the lens is damaged you can simply rotate the lens (or mirror) such that the beam hits an unaffected area. Cheers! Hope you found this useful.

I will go to glass shop to repair or replace one, ask 2 different prices then decide which one price is more afordable . How long it takes that I can use glass again .

Carefully Identify the level of impact. If it is little, it should be rub with wax, and wash. It can then be clean with glass cleaner. But if the impact is much then the glass coat should be replaced
