Non-magnetic Stainless Steel Optical Top
Non-magnetic stainless steel optical top is made of 304 series non-magnetic stainless steel for clean rooms
and non-magnetic applications. The non-magnetic stainless steel optical top provide same features and
benefits that are present on the research grade optical tops. The stainless steel optical top features the finest
performance level of broadband damping that effectively minimizes relative displacement in a wide
frequency, superior structural damping level and ultimate rigidity.
All stainless steel construction
0.25 mm thick honeycomb stainless steel layers are corrugated to
increase its core density and minimize its cell size; These corrugated
honeycomb stainless steel steel layers are vertically epoxy bonded with
stainless steel top skins, stainless steel steel bottom skins and stainless
steel sidewalls to offer static and dynamic rigidity for the
outstanding performance level.
Steel Honeycomb Core Structure
The corrugated honeycomb steel layers are vertically expoxy bonded with a stainless steel top skin,
a carbon steel bottom skin and sidewalls, increasing its core density and minimizing its cell size.
This steel honeycomb core structure provides the highest core density and the smallest honeycomb core cell size, offering maximum static and dynamic rigidity.
Smallest Honeycomb Core Cells
Our steel honeycomb core yields in the highest core density and the smallest honeycomb cell size 2.9㎠, offering the superb rigid table top. As the smallest honeycomb cells contributing to increase the elastic selection modulus, the natural frequency of the optical table tops increases, which the table top is less likely to respond to external forces and unfiltered vibration. Moreover, the higher natural frequency minimizes vibration intensities and deflection under loads, which is critical for conducting optical experiments.Our optical table top is all steel constructed, ensuring the long term thermal stability.
Individually Sealed Mounting Holes
Spill-proof and non-corrosive nylon cups are individually epoxy-bonded under each mounting hole to prevent spilling of liquids from contaminating the honeycomb core.
Tapped and Clean Surface
The table top surface is precision tapped and delicately sanded to provide a non-reflecting surface. Moreover, the surface is completely cleaned to remove residual metal particles and cutting fluids.
Custom Optical Table Tops
We offer customization of optical table tops to meet a variety of customers' needs.
