The updated lens geometry provides:
Better clamping stability
Safer and cleaner machining
More reliable inspection
Higher structural strength
Increased yield and lower production risk
No functional performance impact
This is a textbook example of DFM (Design for Manufacturability):
a small structural adjustment that significantly enhances machining feasibility while keeping optical/RF performance intact.

Anti-Cocking Flange VS. Standard Flange: Installation Differences and Performance Impact

These ultra-small metal components—referred to by the customer as medical blades—are used in high-precision medical devices where reliability, sharpness, and dimensional accuracy are critical.

This Engineering Note presents the measured S-parameters (S11 & S21) of a WR2.2 1-inch straight waveguide operating in the 330–500 GHz frequency band. WR2.2 waveguides belong to the sub-millimeter and early THz regime, where electromagnetic behavior is highly sensitive to: Micron-level dimensional accuracy Surface roughness Plating thickness Flange alignment Mode purity Fabrication repeatability The test

In this waveguide horn antenn component, a slanted through-slot must be cut using Wire-EDM.
However, the original waveguide port extension was too long, and the EDM wire would directly intersect the port wall, causing severe structural damage and RF degradation.

The WR2.8 twist waveguide operates in the 220–325 GHz band.With an internal cross-section of only 0.71 × 0.355 mm, WR2.8 belongs to the Millimeter wave regime where every micron matters. At these frequencies, even a slight geometric deviation—such as a few microns in cavity size or a fractional-degree twist-angle error—will immediately degrade: Insertion Loss Return

The components shown here are 316L stainless steel micro spring–needle assemblies designed for medical devices that interact directly with biological tissue.
