The EOCF has an access-controlled cleanroom with 28m2 of usable floor area and a volume of 60m3 maintained at ISO 6 (Class 1,000). The cleanroom air is completely changed once per minute, making it safe for activities involving large amount of inert gas discharge (e.g. purging during spectral absorption measurements). The facility owns four high-grade optical work-surfaces (one inside the cleanroom, one in the main lab and two in the satellite laboratory) and maintains a core inventory of bench optics. The table decks are Melles Griot 07OTQ501 models measuring 1.25m by 2.0m. Deck material is ferromagnetic stainless steel. Dynamic deflection coefficient, relative table motion and deflection under load specifications are all excellent. The support systems are self-levelling active vibration isolation systems with a load capacity of 2500kg. The table deck will be relevelled for an offset load of up to 250kg. Vertical and horizontal resonant frequencies are extremely low, being on the order of 1Hz.
