Nocturn Katana NVG White Phosphor Night Vision Binocular

The Nocturn Katana NVG combines a lightweight articulating binocular housing with white phosphor night vision. Nocturn Industries officially identifies the platform as the U.A.N.V.B. Katana, short for Ultralight Articulating Night Vision Binocular.

The Katana uses two independently articulating optical pods rather than a fixed binocular arrangement. As a result, each side can move independently while the complete unit maintains a compact profile when folded.

Nocturn builds the current molded Katana housing from a carbon-fiber-reinforced thermoplastic composite and lists a minimum complete-system weight of approximately 415 grams in its lightest configuration.

At the same time, this example adds white phosphor image intensification, giving the viewed image the familiar monochrome white/grey appearance associated with WP tubes.

Nocturn UANVB Katana Design

The Nocturn Katana NVG uses an articulating dual-tube binocular layout.

Each optical pod pivots independently around the central bridge. Therefore, the user can move one pod or both pods away from the eyes without folding the entire system upward.

Nocturn also incorporates individual pod shutoff into the Katana. When a pod articulates away from its operating position, the electronics can switch that side off independently.

In addition, the narrow bridge and articulated pods give the Katana a low-profile shape when stowed.

The design remains visually simple because Nocturn uses a straightforward push-button power control rather than covering the housing with numerous switches.

White Phosphor Night Vision

This particular Katana uses white phosphor, commonly shortened to WP.

White phosphor image-intensifier tubes produce a predominantly white, grey and black image rather than the traditional green appearance associated with older green-phosphor night vision.

However, “white phosphor” does not identify the exact tube manufacturer or performance level.

A complete Katana can use compatible tubes from different manufacturers, and Nocturn’s own product information references builds using manufacturers such as Photonis, Elbit and L3.

For that reason, I would not add any unsupported figures for:

• FOM
• SNR
• Resolution
• EBI
• Halo
• Photocathode sensitivity
• Tube generation
• Tube manufacturer

unless you have the data sheets for this specific unit.

That keeps the listing accurate while still clearly identifying it as a white phosphor Katana.

Dual-Tube Binocular Configuration

The Katana uses two image-intensifier tubes to create a binocular viewing arrangement.

The current housing supports 18 mm MX-10160 format tubes. Nocturn also states that MX-11769 tubes can function after the EGAC pigtail is removed.

As a result, the Katana belongs to the established family of dual-tube analog night-vision binocular systems rather than digital night vision.

The two pods remain mechanically separate while sharing the central bridge and power system.

Meanwhile, the articulating design allows the overall width of the binocular to change depending on pod position.

For your WooCommerce page, the simplest specification is:

Image Intensifier Configuration: Dual tube, white phosphor

If you later obtain the tube sheets, you can add the exact tube model and performance numbers separately.

Ultralight Katana Housing

Low weight forms one of the main characteristics of the UANVB Katana.

Nocturn states that the current molded model can weigh approximately 415 grams, or 14.64 oz, in its lightest complete configuration with onboard power.

Therefore, the Katana housing remains noticeably light for a complete articulating binocular.

The exact weight of your white-phosphor unit may differ depending on:

• Image-intensifier tubes
• Objective lenses
• Eyepieces
• Battery
• Lens accessories
• Installed retention hardware

For that reason, use the actual measured weight of your unit if you need an exact product specification.

For general model information, approximately 415 g in the lightest configuration accurately reflects Nocturn’s current published figure.

Carbon-Fiber-Reinforced Housing

Nocturn manufactures the current molded Katana from a carbon-fiber-reinforced thermoplastic composite.

This construction separates it from the aluminum Katana Ruggedized, or Katana-R.

Therefore, do not describe an ordinary UANVB Katana as having a 7075-T6 aluminum housing.

The distinction is:

UANVB Katana: carbon-fiber-reinforced molded housing

UANVB-R Katana Ruggedized: CNC-machined 7075-T6 aluminum housing

Nocturn lists these as separate models within its binocular family.

If your unit actually says Katana-R or uses the aluminum housing, then the SEO title and specifications should be changed accordingly.

Articulating Pod System

The articulating pods give the Nocturn Katana NVG much of its recognizable shape.

Instead of using a rigid fixed bridge, Nocturn allows each side to rotate independently.

As a result, the pods can fold outward when the unit is not positioned directly in front of both eyes.

Nocturn also links the articulation to individual pod power control.

In addition, the folded arrangement reduces the profile of the binocular when stowed.

This articulation system provides one of the clearest visual differences between the Katana and traditional fixed-bridge binocular night-vision devices.

Friction Lock IPD Adjustment

The Katana includes Nocturn’s patented Friction Lock Interpupillary Adjustment system.

Interpupillary distance, usually shortened to IPD, refers to the spacing between the two optical channels.

Nocturn designed the system so the desired spacing can remain in position without requiring separate adjustment tools.

Therefore, the bridge does more than simply allow each pod to articulate.

It also controls how the two eyepieces align relative to each other.

Nocturn lists tool-free IPD adjustment as one of the Katana’s main features.

For WooCommerce specifications, use:

IPD System: Toolless Friction Lock adjustment

Individual Pod Shutoff

Each Katana pod incorporates independent shutoff behavior when articulated.

Nocturn lists this feature as auto on/off dependent on individual pod articulation.

As a result, moving one optical pod away from its viewing position does not require shutting down the complete binocular.

The feature works naturally with the articulation system and keeps the exterior controls simple.

Meanwhile, a single main push button controls general device power.

This gives the housing a cleaner layout than systems that use several separate rotary controls on the bridge.

Simple Push-Button Power

Nocturn keeps the Katana’s main electronic controls straightforward.

The housing uses a single push-button power control. Nocturn specifically describes the Katana as avoiding additional onboard features such as manual gain controls and built-in IR illuminators in favor of simple functionality.

Therefore, the bridge remains relatively uncluttered.

This feature also helps distinguish the Katana from Nocturn’s more feature-heavy binocular systems such as the Manticore and Raptor families.

For a product listing, the simple description is:

Power Control: Push-button on/off

CR123A Onboard Battery

The Katana uses a single CR123A battery for onboard power.

Nocturn states that the current housing provides approximately 25 hours of continuous runtime from one CR123A battery. The company also lists the design as providing roughly 25–26+ hours, depending on the current product page and configuration.

Therefore, I would write:

Battery: 1 × CR123A

Typical Runtime: approximately 25 hours

rather than presenting an exact runtime as guaranteed.

Actual battery life can vary according to battery condition, temperature, tubes and other operating factors.
