The Melles Griot 070BH522 is a 48″ × 30″ optical table engineered to deliver a stable, vibration-dampened working surface for precision optical experiments and instrumentation. Supplied with support legs (070FB803) for setup and leveling, this system creates a disturbance-free environment essential for sensitive photonics applications. The tabletop employs a triple-plate double-honeycomb construction that achieves unsurpassed stiffness and excellent stability, complemented by an athermalized design that maintains exceptional thermal performance across operating conditions.

– Key Features
• Triple-plate double-honeycomb internal structure for maximum stiffness and minimal deflection
• Athermalized design for thermal stability independent of ambient temperature fluctuations
• Internally damped construction to minimize vibration and resonance
• Sealed mounting holes for convenient cleaning and maintenance
• High resonant frequency (>100 Hz) ensures isolation from typical support system frequencies, preventing energy coupling
• Flat working surface with excellent dimensional stability and minimal relative motion
• Leveling capabilities via included leg assembly for precise instrument alignment
– Isolation System
The 070FB803 leg assembly provides seismic mounting on air springs, effectively decoupling ambient vibration from the optical surface. Horizontally enhanced isolators with long pendulum mechanisms deliver direct horizontal damping. The support structure’s special insulation system reliably attenuates external vibrations, enabling reproducible measurement results in precision optical work.
– Typical Applications
Semiconductor metrology, biotechnology instrumentation, optical component assembly, photonics research and development, and general laboratory precision work requiring vibration isolation and thermal stability.
