YR Optical Table Light-Shielding Enclosures

YR black experiment enclosures use an aluminum-alloy structure. Photographs show a profile frame, enclosed top and sliding doors with handles. Six options are distinguished by source length, width and height labels. No individual SKU photographs or formal engineering drawing are available. The source explicitly excludes the bottom breadboard; an application photograph is not a complete table kit supply list.

Size labels and dimension datum

The source gives YR400-400 as 400 × 400 × 350; YR450-600 as 450 × 600 × 450; YR550-550 as 550 × 550 × 450; YR600-600 as 600 × 600 × 450; YR550-850 as 550 × 850 × 450; and YR600-900 as 600 × 900 × 450, in length/width/height order. Original labels omit units and do not identify external versus internal size. Confirm units, usable space and tolerances; other dimensions are not decoded from model names.

Material and finish

The source specifies aluminum alloy with sandblasting and anodizing, without an alloy grade, panel thickness, profile cross-section, anodized-layer thickness or numerical service life. Durability and long service life are promotional statements rather than loading or lifetime guarantees. Confirm the material and treatment scope for the selected model.

Sliding doors and mounting

Series photographs show two front door panels with handles, partly opened for access. Door travel, maximum opening, track specification, locking and mounting holes are not documented. The bottom breadboard is explicitly excluded, and the circular display pedestal is not an established supplied component. Confirm bench dimensions, attachment and equipment access before selection.

Performance limits and supply

The source uses high-voltage insulation wording without a withstand voltage, test method or certification, so specific electrical insulation performance is not established. Transmission, laser wavelengths, power limits, optical density, damage threshold and protective certification are also unspecified. Aluminum and a black appearance do not establish a laser protection rating. Confirm accessories, ventilation, cable entries and custom dimensions separately.
