The DFB diode lasers of the CWA.L.NB Series are highly-stable, temperature-stabilized diode lasers with extremely narrow spectral bandwidth of typically <2 MHz and <0.005 picometer and coherence lengths of up to 250 meters. As a result of their intelligent laser controller with interface RS-232, these lasers can be integrated seamlessly into applications and controller. Through the standardized Command Line Interface (CLI), you have at all times full control of all parameters of the laser, such as e.g. laser diode temperature, laser powers and currents, operating modes and lots more. The high-precision temperature stabilization to a maximum diode temperature variation of <0.02°K, and the stable power source for the laser diode, enable extreme power stability and very low noise levels. The systems consist of a laser head and a laser controller in the EMC-screened modular housing with supply voltage input 24 V DC, according to industrial standard. The integrated modulation inputs for analog power modulation with up to 1 kHz, and TTL modulation with up to 10 kHz, enable integration into control and measurement processes. As in case of all lasers of the Bluephoton® and Redphoton® series, the laser head can be very simply adapted to customer specifications by the use of the modular principle.

Is the tissue acid free?

Yes all our tissue paper is certified acid free

Do you offer design help?

Our in-house team can suggest colour palettes, ribbon combinations, or box sizes free of charge.

Do you provide a gift-wrapping service?

We supply materials only but are unable to do the wrapping for you.

Will you have a pop-up shop again for Christmas?

Yes on-site downstairs – plenty of parking available. Our Christmas Pop-Up runs 1 November – 23 December 2025 at the same 235 Archers Rd, Wairau Valley location.

Yes everyone is welcome. Winter hours Mon-Thurs 10am-4pm, Fri 10am-3pm. Nov-Dec - Mon-Sat 10am-4pm. Trade buyers, Corporate and the general public are welcome.

Do you sell food packaging?

We do stock some items and if food safe certifed we will state this in the product description. If you are wanting large numbers of food packaging you are better to go to a supplier that specialises in this.

Do you offer environmentally friendly packaging?

More than 50 % of our range is recyclable, or made from post-consumer fibre. Look for the trust icons on each product page and check out or Eco collection also.

Can you match my brand colours exactly for printing on ribbon?

We will suggest the closest colour we have from our stocks but cannot print to match exactly.

Can you print my logo on bags, boxes, or ribbon?

We print locally onto selected ribbons, bags and boxes. Send us a vector file (AI, EPS or PDF). Via website > customise> then complete the quotation form and we will get back to you with pricing.

Do you ship internationally?

We don’t currently as each time we look into it is too expensive via courier.

Why does it not give me the option for local pick-up?

Even though you are collecting you need to enter a shipping address for this to show
