Lens Cleaning Procedure

Cleaning procedure for MD(1.2:1) lens and other MD lenses.

To minimize the possibility of damaging the optical coating or scratch- ing exposed lens surface, we have developed recommendations for cleaning the lens. FIRST, we recommend you try to remove any material from the lens by blowing it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.

A TorayseeTM cloth is included with the lens kit.

Proceed as follows :

1.Always wipe lenses with a CLEAN TorayseeTM cloth.

2.Always wipe lenses in a single direction. Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.

3.Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.

4.If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.

5.Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the cloth.

6.Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.

Order number for a new TorayseeTM cloth : R379058.

Other lenses can also be cleaned safely with this TorayseeTM cloth.

Alternative cleaning procedure for the MD lens, except MD(1.2:1) lens.

To minimize the possibility of damaging the optical coating or scratch- ing exposed lens surfaces, we have developed recommendations for cleaning lenses. FIRST, we recommend you try to remove any material from the lens by blowing it off with deionized air or lightly brushing it with a soft, camel's hair brush.

Plastic lens with multilayer coatings & all glass lens elements.

1.DO NOT spray any type of fluid directly on the lens surface.

2.DO NOT use any dry material to clean the surface (dry rag, tissue, etc.)

3.Use a commercial liquid window cleaner. DO NOT use an aerosol. Other cleaning agents, such as laboratory-grade ac- etone or a 70-30 mixture of ethyl ether and ethyl alcohol may also be used. If you are not sure of the cleaning agent, experiment with a small area of the lens first.

4.Use a soft cotton cloth (cotton diapers laundered several times to remove sizing) or any soft facial tissue (Charmin, Softweve, etc.).

5.When using window cleaner, moisten the cloth or tissue and lightly wipe the surface. Then lightly dry with a new tissue.

6.When using acetone or ethyl ether mixture, proceed as follows : Fold the cloth or tissue several times to form a pad. Soak the folded end of the pad in the acetone. Starting at the diameter opposite you, immediately wipe the coated lens, with very little pressure, toward you in a straight line and off the lens. Do not stop with the tissue on the lens. Wipe at a speed that is equal to the evaporation rate. This is very important to prevent streaking and spotting. Start your wiping at one side of the lens and, with successive wipes, move to the other side. Turn the pad over for each wipe, then inside out. Do not make more than one wipe per clean area of pad. Be careful of the painted edge, since acetone will soften it.

DLP is known for producing sharper images with higher contrast ratios, making it an ideal choice for cinematic presentations.

The projector uses a laser light source, providing several advantages over traditional lamp-based systems. Laser technology not only increases the projector's longevity and reliability but also enables a wider color gamut. This translates to richer, more dynamic colors, enhancing the overall visual experience. With consistent brightness levels throughout its lifespan, the R9001190 ensures that theaters do not have to frequently replace components, leading to reduced operational costs.

In addition to its superior image quality, the Barco R9001190 also incorporates advanced feature sets for enhanced functionality. It supports multiple industry standards such as DCI (Digital Cinema Initiative) and IMB (Integrated Media Block), ensuring compatibility with a wide range of cinema content. The projector is designed for easy integration into existing cinema systems, allowing for streamlined upgrades without extensive system overhauls.

Another notable characteristic of the R9001190 is its built-in cooling system, which efficiently manages heat dissipation, promoting longer operating times without performance degradation. Additionally, the projector is created with a modular design, facilitating serviceability and maintenance. This modular approach reduces downtime, allowing theaters to maintain high levels of operation without significant interruptions.

In summary, the Barco R9001190 is a cutting-edge digital cinema projector that combines high brightness, advanced DLP technology, and a durable laser light source to deliver an unparalleled movie-watching experience. Its integration capabilities, along with features designed for ease of maintenance, make it an essential choice for theaters aiming to provide audiences with immersive and visually stunning films.
