Our method for lens retention virtually eliminates stress concentration introduced into the glass lens assembly when bolting the sight glass into its service position. The Cyclops Industries, Inc. laminated lens assembly is encapsulated and bonded into a lens ferrule; forming an integral one piece ferrule assembly. This one piece ferrule assembly absorbs the bolting stresses instead of subjecting the glass lens to the stress concentrations. This patented retaining method, together with the multi-layered lens, usually a three (3) piece assembly is your assurance of complete sight glass integrity and safety.
Each lens assembly carries a double safety factor of 10 and usually consists of there (3) pieces of fully tempered glass discs which are laminated in a jig to insure a uniform thickness and diameter. They are then bonded into a lens ferrule. The laminating and potting procedures are a time/temperature curing process performed in a controlled atmosphere. All fabricated parts are machined to tolerance so ASME approved plus or minus 0.0025 inch and are made from high quality ASME approved materials.
Complete mill test reports are supplied with each weld type unit as standard practice. Generally speaking each of our weld mounted sight glasses are self-reinforcing to the vessel shell However, it is recommended that reinforcement calculations on all ASME code constructed vessels be carefully checked to insure proper reinforcement of the vessel wall.

The Lens Assembly:
No other sight glass offers this multiple safety factor - three glass disks laminated into a single lens assembly:
The Lens Ferrule:
By fusing the lens assembly to the lip of the ferrule with a Teflon' gasket, and bonding to the inside of the ferrule with a strong, resilient, heat and chemical-resistant compound, the lens assembly and lens ferrule are made into a single unstressed unit.
The single unit is mounted with a hold-down flange and a high quality cushion gasket which provides for an extremely compact mooting assembly.
Through this simplified one-step procedure, it is impossible for a competent mechanic to improperly install Cyclops Safety Sight Glasses.
