Careful preparation over careless purchase
Cinco kits de investigacion de difraccion laser para uno, uno o dos, dos o tres, o hasta seis observadores, que cubren 650, 532 y 405 nm. El kit Protocol convierte el punto en una linea con una varil…
What a kit is for
Stage one is screening, not the experiment. The symbol registry is a screening collection, not a controlled experiment: it is open, self selected and unblinded, and priming is not ruled out. It can only show whether there is a hint of agreement worth digging into. Nothing here settles the question.
Stage two is capture before exposure. Stage three is a randomized blinded arm with control conditions, blind scoring and pre registered hypotheses. Stage three is designed and has not been run. A kit lets you run the observation carefully and add a record. It does not turn a personal session into a controlled result.
Before you go further
Adults 18 and older only. Raise the following with a qualified prescriber before any consideration of practice:
- MAOIs, current or recent
- SSRIs and related serotonergic medications
- Cardiac history
- Personal or family history of psychosis
We publish no discontinuation windows. Timing decisions belong to a clinician who knows your history.
Pointers vendor rated 5 mW, FDA Class IIIa (Class 3R), ray box under 1 mW: do not stare into the beam, do not aim it at anyone, and treat every reflective surface in the room as part of the beam path.

Devoluciones
Los kits sin abrir pueden devolverse en un plazo de 30 días desde la entrega. Los módulos láser abiertos no admiten devolución, ya que son instrumentos ópticos de precisión que no pueden recalibrarse ni revenderse una vez roto el precinto. El envío de la devolución lo paga el comprador. Los reembolsos aprobados se abonan al método de pago original en un plazo de 10 días hábiles desde la recepción.

Laser diffraction research kits
650 nm Laser Protocol Kit (1 Observer)
$199
One observer. The smallest instrument set that runs the protocol as written. Contents: 650 nm deluxe red laser pointer, vendor rated 5 mW, FDA Class IIIa; two adjustable laser pointer stands; glass rods with rubber policemen, 150 x 5 mm, twelve per pack. The second stand is not a spare: one holds the pointer, the other holds a glass rod in the beam, which spreads the dot into a line so the observer scans a form rather than sampling one point. Twelve rods are included because glass breaks. The kit deliberately carries no diffraction gratings and no acrylic set; those are optical experimentation and are carried in the Solo and above. Observation documents are free PDF downloads. Materials notice: contains latex (the rubber policemen fitted to the glass rods are latex) and contains small parts, not suitable for children.
Arrives in 7 to 10 business days, processed within 2. Free US shipping. 18+, for research use.
Ships from Arbor Scientific. Expect Arbor branding on the box, tape and packing slip. No prices on the packing slip. Meridian Optics Lab is the seller of record.
Laser pointers in these kits are vendor rated 5 mW, FDA Class IIIa (Class 3R); the ray box in the Triad and Circle is under 1 mW. Ratings are listed per emitter on each kit. Do not stare into beam.

650 nm Laser Diffraction Research Kit, Solo (1 Observer)
$289
One observer. Contents: 650 nm deluxe red laser pointer, vendor rated 5 mW, FDA Class IIIa; two adjustable laser pointer stands; glass rods with rubber policemen, 150 x 5 mm, twelve per pack; holographic gratings, 500 and 1000 lines per mm, five of each; giant acrylic lens and prism set of 7. The second stand is not a spare: one holds the pointer, the other holds a glass rod in the beam, which spreads the dot into a line so the observer scans a form rather than sampling one point. Twelve rods are included because glass breaks. The 75 mm semicircle in the acrylic set stretches the laser dot into a short bright horizontal line, flat face toward the laser. Line length depends on which piece you use and how far it sits from the laser: moving the optic away from the laser lengthens the line, moving it closer shortens it. At about 3 m from the semicircle the line is roughly 2.5 to 3.6 cm long, not a line across the wall. Observation documents are free PDF downloads. Materials notice: contains latex (the rubber policemen fitted to the glass rods are latex) and contains small parts, not suitable for children.

Laser Diffraction Research Kit, Dual (650 and 532 nm, 1 to 2 Observers)
$399
The Solo bench with a switchable 650 nm red and 532 nm green pointer, vendor rated max 5 mW, FDA Class IIIa, so the same observation can be compared at two wavelengths. Adds Young's slit cards, three per pack. Includes two adjustable stands, glass rods with rubber policemen, twelve per pack, holographic gratings and the acrylic set with the semicircle that stretches the dot into a short bright horizontal line. The second stand is not a spare: one holds the pointer, the other holds a glass rod in the beam, which spreads the dot into a line so the observer scans a form rather than sampling one point. Twelve rods are included because glass breaks. Observation documents are free PDF downloads.

Laser Diffraction Research Kit, Triad (650 and 405 nm, 2 to 3 Observers)
$699
Two to three observers. Contents: 650 nm laser ray box with 1, 3 or 5 beams and its own 8 piece acrylic optics set; 405 nm violet pointer; one adjustable stand for the violet pointer; holographic gratings; Young's slit cards; slide carrier; 50 slide mounted polarizers. The semicircle lens in the ray box case stretches the dot into a short bright horizontal line, and moving it away from the laser lengthens that line. Vendor ratings per emitter: ray box, 650 nm, under 1 mW, laser class 3a; violet pointer, spec sheet 401 nm (sold as 405 nm), under 5 mW, FDA Class IIIa. The ray box is dim, so darken the room. Observation documents are free PDF downloads.

Laser Diffraction Research Kit, Circle (650, 532 and 405 nm, Up to 6 Observers)
$1,090
Up to six observers. Everything in the Triad plus a switchable 650 and 532 nm pointer, vendor rated max 5 mW, FDA Class IIIa, a second stand for that pointer, a second slide carrier and a handheld quantitative spectroscope, so three sources cover 650, 532 and 405 nm. The semicircle lens in the ray box case stretches the dot into a short bright horizontal line, and moving it away from the laser lengthens that line. Observation documents are free PDF downloads.

Field materials and protocols, free download
Thirteen PDF documents, no account needed. Each protocol is available in English, Spanish, and German. Nothing here requires buying a kit. Full descriptions of what each document is and when to use it are at /downloads.
DMT Laser Code Symbols (PDF). The forms people have reported so far, printed for reference. It is a record of what observers drew, not a key, a translation, or a claim that the forms mean anything. If you saw something that is not in it, add yours to the registry. Reading it first counts as having seen the catalogue, and a record submitted afterwards should say so.
