OptomechActivity_Beta04.apk
This is the beta version of an app that includes calculations common during the design phase of a system.

These include:
Sag of a Spherical Surface
Contact Height for different contact conditions (tangential and toroidal)
Contact Stress
Torque and Preload
Length Change due to a Change in Temperature
'Optimal' RTV Bond Gap Thickness based on different approaches (Modified Bayar, Van Bezooijen, Modified Van Bezooijen, Aspect Ratio)
Lens Centerability (i.e. Z-Factor) calculates how likely a lens can be centered using a bell chuck. This is analogous to a lens being mounted between two spacers or a seat and retainer.

Optomech Spreadsheet_001.xlsx
This is a spreadsheet version of the android app. It contains the same calculations.

ZFactor_Beta02.apk
This is the same calculator that is in the OptoMechActivity app.
