Table Performance Calculator
Calculate optical table static deflection, dynamic deflection coefficient (DDC), and worst-case relative motion.
Optical table performance is characterized by two independent properties: static deflection under point loads, and dynamic relative motion under ambient floor vibration. This calculator addresses both. In static mode it computes bending and shear deflection for a honeycomb table supported at Bessel points (L_eff = 0.56L), accounting for skin material, skin thickness, honeycomb core shear modulus, and applied load — relevant when mounting heavy equipment near table center. In dynamic mode it computes the dynamic deflection coefficient (DDC = √(Q/f_n³)) and estimates worst-case relative motion (RM = √(π/2) · DDC · √(W_a) · T) given a table first resonance frequency, amplification factor Q, floor acceleration spectral density W_a from a library of standard environments (quiet lab through heavy manufacturing), and isolator transmissibility T. The relative motion result includes an application suitability rating from sub-nm interferometry through general optical work.
