Cleanrooms for the optical industry

Q: What is cleanroom technology?

The term cleanroom technology covers all technical and organizational measures that serve to control the number of particles introduced into or generated in the cleanroom. This includes the actual cleanroom system with filter and air circulation systems, but also the structured introduction of materials and personnel, the specification of the materials used, the cleaning of the cleanroom, monitoring and much more. Cleanroom technology therefore covers a much wider spectrum than just the cleanroom itself. A defined quality and safety standard is guaranteed through the use and coordination of the various elements of cleanroom technology. Eliminating the damaging influence of particles and microorganisms ensures significantly higher quality and safety. The use of cleanroom technology is therefore increasingly becoming the key to the reliability and cost-effectiveness of products with high quality requirements. Without controlled production processes under cleanroom conditions, many sensitive products can no longer be manufactured today, such as in the semiconductor industry, microtechnology or medical technology, where even the smallest particle deposits render the end product unusable. Another important aspect of cleanroom technology is the reduction of germs and microorganisms, which is absolutely essential in the manufacture of medicines and pharmaceutical products, but also leads to a significant improvement in quality in the food and cosmetics industries.

Q: What is a cleanroom class according to ISO?

When it comes to cleanrooms, there are various gradations that define the particle purity. These gradations are specified in cleanroom classes according to the ISO standard with the numbers one to nine. The lowest cleanroom class ISO 1 describes the cleanest room and cleanroom class ISO 9 approaches the values of natural air in a room. So if you want to achieve the cleanest of cleanrooms, you need an ISO 1 classification. You can find a detailed overview here Cleanroom class table as PDF .

Q: What is a cleanroom class according to GMP?

GMP (“Good Manufacturing Practice”) is an English term that originally comes from the manufacture of pharmaceuticals and active ingredients. Good manufacturing practice” describes certain guidelines for quality assurance of production processes and environments in the pharmaceutical industry. The cleanroom classes according to GMP are based on the ISO standards in terms of particle concentration, but have additional limit values for harmful microorganisms. In contrast to the ISO standard, GMP cleanroom classes are labeled with the letters A to D. Cleanroom class A describes the highest cleanliness level and cleanroom class D the lowest cleanliness level with the highest maximum permissible particle concentration. To get from the lowest to the highest cleanroom class according to GMP, the intermediate cleanroom classes C and B must also be passed through. An overview of the permitted particle numbers can be found here .

Q: What is a cleanroom class table?

A cleanroom class table is an international standard for classifying cleanrooms according to ISO 14644-1 and GMP. The International Organization for Standardization – ISO for short – is an independent organization dedicated to setting international standards for procedures. The internationally approved particle sizes for the different ISO cleanroom classes and cleanroom classes according to GMP are listed here. So if you want to achieve the cleanest of cleanrooms, you need a cleanroom classification according to ISO 1. To achieve this, samples with 10 or fewer particles with a size of 0.1 micrometers per cubic meter must be detected. From then on, the scale allows for more and larger particles. In the ISO 5 cleanroom class, which meets the very strict requirements for microchip production, for example, up to 100,000 particles of 0.1 micrometers may be measured. Particles of 1.0 micrometers may not exceed 823. Cleanroom class ISO 9 is the “worst” cleanroom class and is considered normal room air. In these rooms, particle sizes of 0.1 micrometers are no longer considered. Allowed here are 8,320,000 or fewer particles of 1 micrometer and 293,000 or fewer particles of 5 micrometers.

In many industrial sectors, such as the optical industry, high-precision manufacturing processes determine the quality and function of sensitive products. Even the smallest particles or temperature fluctuations can affect lenses, prisms, coatings and components.

With our modular CleanCell4.0 cleanroom, you can achieve cleanroom classes up to ISO 5 and create a particle-free environment with precisely controlled temperature and humidity. The room-in-room system can be flexibly integrated into existing production halls and expanded at any time.

For less critical applications, our CleanFlowCell cleanroom tents and CleanEasyCell CNC Cleanrooms offer an economical alternative: quick to install, flexibly adaptable and yet reliable in terms of particle protection.

Whether for the production of high-precision parts, optical components or sensitive surfaces – a controlled cleanroom environment ensures stable processes, the highest product quality and maximum cost-effectiveness.

Our cleanroom solutions

Clean room systems

Our CleanCell4.0 "room-in-room" systems are equipped with modern control and air conditioning technology and meet the highest requirements of cleanroom classes ISO 5 to ISO 9. The systems are suitable for high-tech areas of electronics, the semiconductor industry, microtechnology, optics and much more.

Cleanroom tents

Our CleanFlowCell cleanroom tents offer you a quick and cost-effective solution for preventing contamination. They achieve an air quality of cleanroom class ISO5 to ISO9. Benefit from our practical standard sizes, modular design and plug and play.

CNC Cleanrooms

With our CleanEasyCell CNC Cleanroom, you can quickly achieve a controlled, closed environment up to ISO 8. An individual modular system with self-assembly and operationally efficient filter performance ensure consistent, defined technical cleanliness at a very attractive price.

laminar flow cabinets

Our CleanProCel cabinets and flow boxes ensure a safe environment with optimized air flows. The workbenches and table tops offer maximum product and personal protection in a small space and are particularly suitable for sensitive production and measuring tasks as a delimited clean air area.

Construction of a cleanroom.

We accompanied the construction of a cleanroom system with time lapse and drone. In 2.5 minutes, you can see how a cleanroom system measuring over 500 m² is delivered in individual elements and assembled, including air conditioning. In this example, the cleanroom was planned with 16-meter-long trusses to create a self-supporting surface over the entire length.
