Non-magnetic Stainless Steel
Non-magnetic stainless steel optical table 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.
Smallest Honeycomb Core Cells
Our honeycomb core yields in the highest core density and the smallest honeycomb cell size 3.2㎠, offering the remarkable rigidity of the optical tables. As the smallest honeycomb cells contributing to increase the elastic selection modulus, the natural frequency of the optical tops increases. Since our optical tops have the high natural frequencies, environmental vibrations are reduced, external forces are hindered to produce deflection and vibration isolation systems are effective. Moreover, the higher natural frequency minimizes vibration intensities and deflection under loads, which is critical for conducting optical experiments.
Individual nylon cups are epoxy-boned under each mounting hole to prevent
spilling of chemical or foreign substances into the honeycomb core.
Clean Surface with Mounting Holes
We delicately sand the optical top surfaces to offer clean and non-glare work surfaces.
And M6 mounting holes are tapped on 25 mm centers for users to mount their applications on the optical tops.
Custom-made Optical Tops
DAEIL offers customization of optical tops to meet a variety of customers' needs.
Compliance curve was measured on 2400 x 1200 x 300mm Research Grade optical top
The primary goal of designing optical tops is to construct the optical tops as rigid as possible, and DAEIL SYSTEMS is proudly to insist that our honeycomb optical tops satisfy customers. Our super, rigid optical tops minimize relative motion through the structural damping (honeycomb structure); consequently, the honeycomb structure increases natural frequencies of the optical tops, effectively resisting deflections and minimizing remaining vibrations that passes through the vibration isolation.
The performance of DAEIL optical tops are measured by the compliance curve. The compliance curve indicates how the optical tops rigidly damp static forces (addition or movement of applications) and dynamic forces (environmental vibrations). As the compliance curve is closely related with the optical top performance level, DAEIL optical tops assures the maximum compliance level as the graph represents.
